3D Printed Hair Tie Stand

Above: Design shown from above
Challenge: Student wanted to create a hair tie stand to store hair ties that were all over the place. The design needed to be flexible and personalised.
Background: Coming back from the school holidays a Y5 student approached me and stated that they had an original design which they had thought of during the break, to solve a practical problem. This was the students first original design meeting the expected classroom brief.
Level of Difficulty: Low - the design was straightforward and featured basic designs from the main Tinkercad interface that were then adjusted to complete the design. The original design was not personalised, so the name was added last to reflect the student and increase the difficulty
slightly. Additional features could have been added to the base (such as multiple words or extra shapes).
Timeframe: This design was an six hour version, with an 8mm nozzle as stated. Obviously the size of the cone was variable and could be redesigned depending on the choices of the students and the stand wouuld still function.
Size: 11cm long, 9cm wide, a width of the base plate of 5mm and a height of the cone section of the design of 9cm from the base plate.
What we would do differently: Very little, the design was original, which fits the general brief. It addressed a problem or an issue that was relevant to a student and was successfully solved by a print.
Next steps for the students: The student was able to idependenlty complete the process without any teacher interaction. With the next step would be something more complicated, another original design that would potentially include interlocking pieces or working/moving parts.

3D Printed Basic Tap Design

Tap with block insert pictured right
Challenge: To create from scratch a tap (faucet for our American friends) that would be viable and working suitable for use with a worm farm.  Students involved were Y2-Y4.
Background: Junior School students from another classroom had been creating a realistic sized model of a worm farm for a showcase (parents eventing).   They had mocked up a model but the teacher as looking for something extra to complete the display.   Our class released two students to work with the junior school students.  For both sets of students this was their first original Tinkercad and 3D Printing designs.
Tap with square insert to act as block
Level of Difficulty: Medium to High.  The inital design process involved a challenge to the students to produce a working tap.  With little design experience they attempted to design a working tap - however they were redirected to keep it simple, by producing a tube shape with block that could be inserted into it to act as a block (as shown above).  Once this was successfully printed the students would then start to examine the process of engineering related to a tap and more advanced.  Ideally this would lead to a repeat of the process where the students would look at a more complicated solution.  One of the basic designs 'block' piece did not seal the pipe successfully the student had not considered the implications of producinga square block instead of a round one.   The
Timefame: Initial prints in the series (not featured) were 45 minutes.  This allowed the students to refine their design (as pictured) which put the design (including the block) at two and half hours.
Size: 7cm in length, 2cm high (the deisgn was of course hollow which included significant internal rafting which then needed to be removed using pliers). 
What we would do differently: This print is a work in progress.   The intended progress is to give the students design experience and advance them forward in the process.  Although the 'tap' concept with initially daunting the students concerned have made an excellent start and are already looking to refine and improve their design, hopefully showing a considerable improvement and refinement as they progress with the ideas.

3D Printed Animal Bait Station - Personalised

Final Print with name aspect visible.
Challenge: Having completed the design, testing and refining of a student created 3D Printed Bait Station, the students were considering ways in which to personalise the creation.
Background: This design and process has been described indepth before on previous posts on this blog, the difference was an addition was made, as shown in photographs, that the name of the person (in this case from the Taranaki Regional Council, the pest control officer was added to the base of the print) was added.  This was for the purpose of identifying the bait station, and obviously this could be modified to introduce the name of a company or organisation or even number the bait stations in sequence for recording purposes.  It was also considered that the students could produce something similar for fundraising purposes, with the name of a company, or individual added to the print run.
Level of Difficulty: Low - the print has not changed since the development of the extended feet, the only addition to this version was the naming which was completed with basic lettering that was taken from the main interface of Tinkercad, this took the student within three minutes to complete.
Above: Hedgehog in action at night
Timeframe: Ten hours (original print design) adding the lettering did not affect this in a significant way.
Size: The lettering likewise did not alter the dimensions of the design significantly, evidence from the night vision camera has identified that the Hedgehogs are unable to dislodge the bait stations from the ground by tipping them over, as once the station is buried in the ground with the
legs featured above enough resistance is created to prevent the toppling of the bait station.  We have photographs of hedgehogs attempting to do just this to allow them better access at the bait.
What we would do differently: The students will be moving on to other projects as this one has been mastered, the only exception would be the production of individual bait stations in some form of economic process (such as a student market day) or gifts to the appropriate organisation associated with the school.

3D Printed Student Business Projects - Part Two

Above: Conditioner holder with lid.
Challenge: For students to produce a container/packaging for a classroom created business project.  The container needed to be able to hold liquid or cosmetic products.
Background: This is the final draft print of the classroom set designed described previously.  In these two examples students were looking to create containers that would hold samples of conditioner and lip balm.  (the cosmetics were to be produced seperately in the classroom and this is the sample box).
The students concerned were a Y4/5 classroom - nine and ten year old students.  This was their first 3D Print designs, which were created by students using Tinkercad, for the first time. Students were producing a prototype with a base and a lid, and experimenting with the lid being able
Above: Lip Balm storage container
to be dropped into the base to seal the container.
Level of Difficulty: Medium - the issue consistently with this set of designs and prints was the lid.  The two lids in the case of both of these prints were no exception.  In both cases students had designed the lids without due consideration for a reduced inner lid which would allow the lid to drop into the base.  In the case of both of these designs students are going to re-design the lid and drop down the size of the lid insert so the base will work with the lid clearly in place allowing the concept to be successfully completed.
Timeframe: The heart shaped box was two and a quarter hours, the taller box featured above was five hours (both print time included the lids both printed at the same time.   This was on the normal print setting, with additional rafting to support the inserts.
Size: Right - the heart shaped box has a width of 6cm across a height of 2cm, the lid being slightly smaller.  The larger container had similar dimensions with the exception of the height which was 8cm. The width of both prints were 5mm and was above right from a size perspective.
What would we do differently: The boxes/containers need to have the lid reprinted because with nearly all other objects in this set the students underestimated the need to reduce the inserts allowing the lid to drop into place.  The students as noted are going to redesign the lids and re-print them reducing the inserts, the bases are remaining, so overall the prototype succeeded in meeting the breif.

3D Printed Student Lip Balm Holders

Above: Rounded Lip Balm Design.
Challenge: For students to produce an original working container that was suitable for holding liquid or lip balm.  Created by Y4/5 students in New Zealand who were nine and ten years old.
Background: Next term our cluster of four schools have a showcase where the students have worked this term on a significant project.  The class next door are making authentic products to showcase and as a result the students used Tinkercad to create a container for their product.
Above: Outside 'rafting' clearly visible
Level of Difficulty: Medium - both these designs needed significant adjustments which the students will repeat.   Both included text and design that were printed on the outside of the 3D Print, which contrasted with designs that have the lettering inserted into the base of the design.  These desings in addition were round in shape instead of being square.  When 'rafting' was removed the lettering itself would be removed from the shape, negating its effect.
Timeframe: For producing something such as this with an 8mm nozzle (various designs are shown all with slightly different timeframe) you are looking at a six to eight hour print time.  The prints are essentially variations of the same theme which is why I have group them all together in a similar post.  As a consequence these prints for various reason will be reprinted shortly.
Note lettering starting to be missing detail
Size: As above and shown in photograph.  The lids are in the 4cm to 6cm range, the base have a range from 6cm-10cm with a height in the range of 10cm to 20cm.
What we would do differently: The lettering will be redesigned to reflect the size of the prints - and an attempt to shift the lettering from featuring on the outside of the print to the inside.   This is illustrated in the print to the left which the lettering is starting to show signs of missing parts of the font.  We used an 8mm nozzle for this print, on reflection we could have shifted to a 4mm nozzle and this would have allowed more detail into the print - however the problem would have been that this would have doubled the print time and there are a number of prints in this run for the class of students that need to be completed, and this afterall is a prototype to test the production skills of the student and allow them a first attempt at 3D Printing.

3D Printed Student Lip Balm Holder

Heart Shaped Box viewd from above.
Challenge: For student to produce a functional lip balm holder, with a working lid.  The students who created this project were nine years old (working at Y4/5 level in New Zealand)
Background: This is the second featured print from the series previously described here.  The idea was for the student to produce a product that could be marketed to the general public and this is a test pot, featuring the lip balm with the logo of the business allowing people to sample the produce.
Lid wtih rafting present.
Level of Difficulty: Medium - although the print is not significant in size the design featured a working lid that was required to be printed seperately and work together in conjunction with the base.  This required a drop down lid with an insert/lip that would allow it to sit ontop of the base.  The print was successfully completed with the base the first time.  The lid when the 'rafting' was removed (by the teacher with pliers) an adjustment needed to be made with the insert as it required a further layer of removal, this was completed by the parent of the student who designed it, in his workshop at home.  (Had this not been possible we would have simply reprinted the lid with an decreased 'lip' insert which would have been in the one and a half hour to two hour timeframe).
Timeframe: Eight hours - 8mm nozzle size, with standard PLA.   The process was completed by a Tinkercad design followed by a conversion to Cura (the new updated version) and then printed.
Completed print with lid
Size: Both designs were printed 1cm high, a height of 9cm and 6cm across.  The idea was that they would sit in the hand of the person holding them.
What we would do differently: The students have produced something that has solved the brief in a really positive experience for the students.  They were able to design and create an original Tinkercad project which then translated extremely well into a 3D Print.  It was the students first experience with 3D Printing and has allowed an original eye catching prop to be completed for their presentation.

3D Printed Student Business Project Containers

Container and lid before rafting removed
Challenge: For student to create and print a unique personalised container that was suitable for the holding or storage of liquid (conditioner).
Background:   All of our students have a significant showcase coming up.  As part of this the students in the classroom next door are producing a range of products that are unique which they create which they would like to brand.  3D Printing allows them to engineer and design their own products (using Tinkercad) and then create them.  The students in this case are nine and ten year old students.
Two lids, reprint on the right
Level of Difficulty: Medium.  The students were designing for the first time and were able to have students assist the process who had 3D Printing experience.   There had to be a re-print of the lid as, as the drop down aspect of the first print did not work.  It did fit however the fit was extremely tight and wouldn't have been easily removed.  The student was made aware of this issue and created a second lid, which was a seperate print, the internal aspect of which fitted much better for the purpose of the print.  
Timefame: Ten hours for both the base and the lid in this case.  The second reprint of the lid, when it was just produced on its own took two hours.
Size: Ten centimetres for the height of the container, 6cm across.
What we would do differently: Very little.  The students concerned meet the brief that they had created and were excited with the results.   It was a successful print, allowed for a degree of individualism and created a unique print for the student.  The student had not had significant previous experience using Tinkercad but was able to confidently produce the print.  (The teacher had to remove the rafting using pliers on this occassion).

3D Printed DIsplay Prop

Challenge: To create or produce a prop for a school display.
Background: Our students have a significant Science presentation coming up, where the local community is expected to attend.  As part of the presentation we are looking at incidents of using the 3D Printer to show off our students creativity.  Given this brief,  for this first time ever in the history of this site we printed a pre-created model that had little or no input from our students.
Level of Difficulty: Nil - this was a pre-created model that was sourced from Tinkercad.  The students only challenge was to re-size the model as the initial model was too small to be effective.
Timeframe: Ten hours - 8mm.
Size: 10cm in length and 6cm wide, with a depth that varies from 5cm to 7cm.
What we would do differently: As the classroom teacher I really struggled with the concept of this, and the balance between producing something for a display and creating something original.   In the end despite the students selecting the image to print by using another persons design it has significnatly reduced the creativity involved.  The students themselves would have struggled to produce this themselves

3D Printed Animal Bait Station: Take Three

Redesign with focus on extending legs
Challenge: To build a bait station that allows the recording of nocturnal animals at our School that is able to resist being tipped over by a hedgehog.
Hedgehog at School tipping bait station
Background: As detailed in the three previous posts the students have been creating 'bait stations' at allow nocturnal animals at school being photographed by a trail camera.  The students have identified that Hedgehogs (which are considered a pest here in New Zealand) are a significant factor at our school.  We have recorded evidence of the hedgehogs tiping over our bait stations by standing up and pushing them over, allowing them to access the bait.  In the last two revisions of the print the student was targetting the legs of the print, as larger legs are intended to provide stability to prevent the hedgehog from being able to tip the bait station over.
Bait station in foreground in place
Level of Difficulty: Low - this version of the print has replaced a 'spike' version of the legs with a cyclinder shape.  Despite numerous attempts at printing those they had not proven successful (see previous prints0 so the student opted for this design with the intent to bury them in the ground.
Timeframe; Ten hours - the modification with the legs did not significantly alter the print time for this project.
Size: The intention with the 'spike' version of this project has not added to the size of the legs, the design of them has shifted to a cylinder shape as can be clearly seen in the photographs.
What we would do differently: This variation of the print solved the issue as by burying the bait station in the ground it was possible to ensure that the Hedgehog was not able to tip the station and remove the bait.  This was a positive creative use for the 3D Printers to resolve an issue.

3D Printed Animal Bait Station: Take Two

Take Two prior to rafting removal
Challenge: To build a bait station to allow the recording of nocturnal animals.
Background: In monitoring the number of nocturnal animals at Auroa Primary School the students from class have identified Cats and Hedgehogs as two animals requiring monitoring.  As part of this the challenge has been to 3D Print bait stations (with peanut butter for the Hedgehogs and Cat busicuits for the Cats).  Both animals have shown the ability to tip over the exisitng bait stations (as illustrated in the photographs).   Students have produced bait stations but not currently one that has shown the ability to resist being tipped by a Hedgehog or Cat.
The spikes, once rafting is removed
Level of Difficulty:  Low.  This is a modification of a previous print that has not worked and students are trying to improve the ability of the bait station to avoid being tipped by the animal.
Timeframe: Ten hours with a 8mm nozzle print.
Size: 10cm across, with an 8cm cylnder and then spikes (see picture) designed to a depth of 8cm to provide more stability than the original print.
What we would do differently: The spikes, which were intended to provide additional stability, failed.  The 'spike design' was not able to be printed correctly, despite several attempts with this version of the bait station.  The student has opted to attempt to print a cylinder version of the spikes, and then to bury the entire base of the design in the ground.  The idea is that this should provide enough support to prevent the animals from tipping the bait station, allowing them to be successfully photographed.
 Left: A cat shown tiping the original designed 3D Printed bait station.
Right: A hedgehog tipping the bait station at three o'clock in the morning.

3D Printed Animal Bait Station

Challenge: For students to create a unique 3D printed bait station.
Bait station as viewed from below
Background: Students are looking to use a tracking camera to record the amount of animals that are located in the school.   As part of the process a bait station was required.   There are feral cats located in the area, and they were able to wreck the existing bait station.   Students working in a group created an original Tinkercad design with the intention of attratcting cats without the cat being able to easily access the bait - allowing the cat to be photographed for recording purposes.
Level of Difficulty: Medium, the design was created from scratch and the students involved had previously been creating other designs in the series.  This finished version was the first version of the print.  The students had access to other students in the classroom who have used the printers.
Timeframe: Eight hours on a 8mm nozzle print.  The design needed to incorperate several features, a cylinder design to house the bait (in this case, cat bisuits) and a platform with the ability to allow it to be placed in the ground.
Size: 10cm across, 6cm high, 5mm across - platform.  The cylinder for the bait was 4cm across and 7cm in height.  These sizes were worked out on the basis of the problem that the students were looking to solve.
What we would do differently: The design currently relies on the weather remaining dry as there is no lid.   This is a consideration for an improvement if the weather proves to be wet in the future.

The feral cat activity would indicate that the cats are quite vigourous in attempting to access the catfood.  There is a significant question about its durability under pressure.  Given all the circumstances the students have completed a challenge with a innovative and creative design that specifically addresses an issue that needed to be solved.

Left: Actual footage from the first attempt at using the Trail Camera to identify and record feral cats in the school.   The yellow box that is in front of the cat has been dragged from the position that it was placed in.

3D Printed Jewellery Box - Additional Decorations

This is not a seperate post, it is detailing some of the additional decoration that was added to the Jewllery Box created this week.  The student who is a Y5 (ten year old) student created the base and the lid in two seperate prints detailed on this site taking twelve hours for the box and eleven hours for the lid.   This was the students third attempt at 3D printing.

 Left: Jewellery box (with rafting removed from under the handle).  Student purchased stick on jewellery accessories from a bargain shop ($2) shop.  These had adhesive labels which peeled off to allow the decoration to be stuck to the box.

The box as noted previously went through six drafts before the final design was completed.
 Left: Viewed from the other side the box featuring the decoration.  The adhesive material on the outside decorations was able to be attatched easily to the printed box.

Transparent green was the PLA filament that was used to print with an Ultimaker 2+ with a 8mm nozzle.   The combined print time for two seperate pieces was twenty hours.

Left: The student wanted to make this box into a functional Jewellery box and to do so decided that padding would be required for the internal part of the box.  She purchased the padding cheaply from a $2 shop, the right hand side was designed for earings.  The left had side was for general jewellery.

The lid once 'rafting' was removed was able to sit precisely on the top of the box.

3D Printed Individualised Jewellery Box Lid

 Above: The lid prior to rafting removal
Challenge: To produce a working and individualised lid to be used in conjunction with the box designed in the previous print.
Background: Student was looking to create a jewellery box, individualising it in a way that reflected herself.  The lid needed to reflect the dimensions of the box as the two had to work in tandem.  The student concerned with this project is ten years old and its her first mid level difficult project having already completed projects based around a name plate and a desk organiser.
Level of Difficulty: Medium - in this example the challenge was not to build simply a standard lid but to ensure that it was personalised for the student, the student opted for her name and a pair of stars visible in the photo.  These were both created using the default interface on Tinkercad, and took fifteen minutes to create.
Timeframe: Eleven hours, the layering of the detail on the stars and the name lettering ensured that the lid as a seperate piece took nearly as long as the base to produce.  8mm nozzle.
Size: 14cm by 11cm with a depth of 1cm.
What would we do differently: The lid has some basic edging but does not have the detail or the drop in lip feature of other boxes that have been designed of a similar nature in the class.  As a consequence the lid has to sit ontop of the box instead of being held firmly in place as part of the design.  The student however was not concerned as given the nature of the print was thrilled with how it turned out.  In the photograph above the handle 'rafting' is still in place, and has yet to removed, knocking this through would allow the handle to gripped properly.

3D Printed Student Jewellery Box

Box viewed from above
Challenge: For a student to design, from scratch, an original 3D Print of an object that would have a use and a purpose.  Design need to be built by the student (using Tinkercad) who was ten years old.
Background: A student who had created a name plate, and then a desk organiser was looking to create something else original.  She had seen designs from other students for iPod Boxes and Edison Robot box holders and decided to create something that she could personalise in this case a jewellery box.
Level of Difficulty: Medium - this design went through a number of drafts before the final print run.  The student designed six versions of the box before the print was
completed, five of the designs would not have work or the base would not have printed successfully.  This was the students first project of a more advanced level.
Timeframe: Twelve hours - this is similar to other prints in this series, completed with an 8mm nozzle.
Size: 14cm wide, 11cm high and a height of 5cm.
What would we do differently: Not a lot.  The internal bar between the sections was originally thin but this was picked up in the review of the print.  The original design had a print time of a 30 hours however this was because the height was intended to be in the 20cm-30cm range.  As a result of this and the importing of the print from Tinkercad to Cura to determine the printing time and drawing a mock up of the design, relative to its size.  Given that the purpose of the box was intended as a jewellery box this clearly would not have worked - however it was a positive experience for the student to realise and identify this.

3D Printed iPod Box - Delux

Above: Box with rafting still attatched
Challenge: Student wanted to create an original project as a storage box for his iPad.  He was challenged to come up with 'next level' additions to the design to incorperate new features that had not been previously created in the series of boxes and storage items being created in class.
Background: Student was responsible for the Mothers Day Box in this series of prints, featured in detail on this blog.  He has mastered the drop down lid for 3D Printed boxes.  He is a student who is nearly ten years old.  He is using 3D Printers and projects for the first time in class this year.
The box lid and handle
Level of Difficulty: High - for a students design on this machine this is about as challenging as it can get.  A basic box design incorperates a number of additional features - a internal wall to assist storage, a hole in the base of the box to allow the iPod to be charged when the box is closed, and a drop down lid with a lip that sinks down into the box.
Size: 19cm long, 8cm wide and a height of 8cm.  The lid was slightlty smaller with an internal lip the required the removal of rafting.
Timeframe: The main box was a twelve hour print, the lid was six hours. 8mm nozzle as detailed previously.
What would we do differently: The student concerned has previously mastered sinking lettering into the base of the box or object that he has created to personalise them.  In this instance he choose not to do this however it would have been a simple matter to include this.
Feedback from the student: The student who created this project was asked to talk about it and show the object which is the video that follows. (This video was informally shot by students in front of the green screen in our hall, this screen is a painted wall 8m across, 7m high and a depth of 2m from the green carpet tiles that come out from the wall)

Auroa Primary Technology Projects 2017

These projects are not directly 3D Printing Projects - they are showcasing some of the technology that students who are 12 and 13  year olds can complete at Auroa Primary School.  They have one Friday a week for three quarters of the school year where they

Previously we created speakers for 3D Printing that were a major project in 2015.   These speakers required 100 hours or so of 3D Printing to print the feet, handle and speaker covers.  For 2017 our students project was to produce these speakers as described below: the intention is the speakers will integrate some form of 3D printing accessories but students at present have laser cut the speaker from wood.

3D Printed Edison Robot Box - V3.0

Challenge: The Edison Robot is delivered in minial packaging, a simple fold out cardboard box that is designed to be disposed of once the robot begins being operated.  One of the issues discussed with the students was ways to transport the Edison Robot (which requires to operate just batteries and a programming cable).   The Edison Robots are high use items so we were looking at designing a way to transport them easily from location to location within the school.
Background: As mentioned above.  We have a set of robots that are high use items that are required for use all around the school in different classrooms.   The idea was a way in which we could have students take the robots safely (although they are very durable) from location as needed.
Level of Difficulty: Medium - the design was original however variations of this design have been mastered by the students Y5/6 (nine and ten year olds) in my classroom - however this is also a purpose built design from scratch.  
Size: Length 25cm and height of 15cm.  This box was created with a depth of 7cm.
Timeframe: The box itself was a twelve hour print.  The lid was eight hours.  The nozzle is set at 8mm which is intended to significantly speed up the printing process.
What we would do differently: The box lid was created as a by-product of another print.  There is not a specific area or storage space for the cable, although this programming add on is not always required when the robots are used and the batteries are preloaded into the machines before a class uses them.  While the lid fits perfectly with the box the handle is not the most practical for the students to use to carry the box (most lift the box from underneath).  The idea has been floated for a latch of some sort to allow the lid to remain in place, or an adapted handle that would make the carrying more practical.

3D Printed Edison Robot Box - V2.0

Edison Robot Case Version 2.0
Challenge: Student had designed the previous print in this series as a stand/box for an Edison Robot, his original design featured a single compartment for the batteries and the coding cord, and the robot itself was too big to fit into the box.  These issues were intended to be addressed in this improvement.
Background: Following feedback from staff over the first print the student was challenged to make improvements on the design to make it more user friendly.
Level of Difficulty: Medium - this is an update of a previous print that has worked, but this student is making adjustments with the intention of making improvements.  The original design had a combined battery and cord space and he wanted to seperate the two into distinct areas.  In the first print/design this area was a combined space and the robot was not able to fit into the space so it was tilted, the student was looking at a way of stacking multiple robots in a space with all thier equipment.
Size: Length 16cm, width 10cm and a height of 3cm for the sides.
Timeframe: Seven hours to print (8mm nozzle).
Process: Unsatisfied with the original design the student modified it in Tinkercad to make the changes that he thought was required.
What we would do differently: Although it isn't perhaps obvious from viewing the photographs supplied the batteries were originally intended to be standing up in the space above occupied by the connection wire - however this space was only able to have three batteries standing in the area vertically which was the intention.  The student has indicated that he can make improvements and will redesign the print accordingly.   He has been asked to think about ways in which multiple robots can be stored and the boxes linked together and also the possibilities of individualising each box for ease of location of specific robots (as we currently have a dozen at our school).

3D Printed Edison Robot Box

Edison Robot in storage with additional items.
Challenge: The Edison Robot comes as a low cost pre-programmed Robot for use in the classroom/education.  The emphasis on packaging is minimal so when the device is unboxed it is ready for use.  It also comes with additional items that are required to run it, batteries and a headphone set.  The idea behind this design was to introduce a storage space for the Edison Robot where these additional items (and the robot) could be cleanly stored when not it use.
Background: Student had previously designed low level design and was looking to extend himself with something more creative and unique.  The school has a set of thirteen of these robots all of which have additional items that are required for them to run, the teacher concerned thought that the idea itself was excellent and would really help the storage of these robots.
Level of Difficulty: Low-Medium, the design itself was straightforward consisting of basic and common shapes with a divider in between (as shown above).  However the student already has ideas to increase the complexity of the design based on the prototype that has been printed.
Size: As shown a length of 15cm a height of 10cm and a depth of 3cm.
Timeframe:  Six hours to print. (8mm)
Process: Tinkercad, main interface then into Cura and then printed on an Ultimaker 2+.
What we would do differently: This was the first design and the idea was essentially a prototype, the student as the print run was being completed was already considering alterations to the design, either increasing the size of the space for the Edison, which at present in slightly smaller than the robot, as shown above.   The other consideration is to raise the depth of the sides of the box which currently are 3cm.

3D Printed Egg Cup

Eggcup with rafting holding beak in place
Challenge - Student was interested in creating a practical 3D Print that would have a regular use.  She enjoys eating eggs for breakfast and had seen the previous design of a Egg Cup.  She believed that she could improve on the design, and did so using the basic Tinkercad design interface.
Background: We encourage students at our school and in our class to create original designs that are practical and original.  If a design meets this brief then we take an opportunity to print it.
Level of Difficulty: Medium - this was designed from the basic Tinkercad Interface of which the chicken feet and beak are basic designs.  There was innovation with the hollowing out process and the sizing of the design.
Size: Width of 6cm, length of 6cm and a height of 6cm.  
Timeframe: The print took five hours -  the difference that this has made, the original design in this series was a nine hour print (both with a 8mm nozzle).  This was a more compact design as the original had wings and an extended beak etc.
Process: Most of the key features of this design were created using the basic interface options available on Tinkercad.  It was the students first original design for a Y6 (11 year old student) and as a consquence the student wanted to keep the design simple to ensure it was successful.  As per most designs here it was a process involving Tinkercad/Cura and then printing on an Ultimaker 2+.
What we would do differently: Nothing.  The design was a considerable improvement on the original, it was more practical, had better balance and served a better purpose.  The student was thrilled with the result and it would be considered an extremely successful print.

Y2 3D Printed Cookie Cutter

Completed Design - Rafting to remain as part of design
Challenge: Looking to engage a Y2 student in a project it was decided to use 3D Printing to involve him in the creative process.   The student was able to select the image for his 3D Print which was then converted with the intention of it becoming a cookie cutter.
Background: The process that was used for the project came from this site, with the steps described under the 'beginners guide to 3D Printing'.
Level of Difficulty: Low - the student was six years old, so the conversion of the SVG file for its import into Tinkercad was conducted by an adult as it was felt that the student would not be able to do so independently.   (It should be pointed out that he was not given the opportunity and probably could have done so with instruction).  If you look closely at the design you can see the top left hand ear of the cat is in fact slightly seperated, ideally the original design would have a slightly thicker outline to allow for a thicker print.
Size: Strictly speaking for a cookie cutter this is quite a big design being 10cm across and 20cm high.
Timeframe: Four Hours - again as has been repeatedly stated we are now using a 8mm nozzle.
Process: An image on a google search, converted into a SVG file for an import into Tinkercad.  This was then stretched from its original flat design into a shape that would allow it to be used as a cookie cutter.
What we would do differently: The rafting was delibrately left on this print to help with the pressing of the print into the cookie dough.   As noted the width of the design ideally would have been slightly greater width of it to make the design more robust, however the creator was extremely pleased with it, including as a reason the fact he could make really big cookies from it.

3D Student Printed Desk Organiser - Take Three

Design prior to removal of all rafting
Challenge - previously on this site we have detailed the design and creation of various desk organisers for students to use to keep their stationary.  These have been individualised by the students and we were looking at an eight hour or so print time.  We also decided to encourage the students to look at producing smaller versions.  This item came out of this process.
Background: Student based her design on similar designs from other students in the classroom.  She focussed on individualising it by having her name sunken into the base of the object.
Level of Difficulty: Medium the student letter and font was made as part of the shape and the shape itself was oval.  Not all the letters were able to be sunken to the same depth due to the design.
Size: The student organiser was 10cm heigh with a base of 6cm across.
Timeframe: Four hours - this was halving the time for the larger pieces.
Process: Student was producing her first next design using Tinkercad following a name plate.  She was clearly influenced by this design in the series, however the size aspect of it made it unique.
What we would do differently: The students object was limited by what it was able to hold as a result of its size.  The lettering worked extremely well and the student was able to produce this independently.  As a consequence she was thrilled with the design and able to produce an object that she was proud of.

3D Printed iPod Case

Above - Box and lid together - prior to removal of the 'rafting'.
Challenge - Student who had previously completed the expected introductory tasks was looking to move towards creating more creative and technically difficult print.  He identified that he had an iPod that currently sat on his desk at home when not at use and decided to print a box to use for storage.
Background: Student created the original idea from scratch and as a consequence designed it, measured it and throught about the process and the end product.
Level of Difficulty: Medium.  This was created by a nine year old student however it required a number of compartments and details that required specific measuring and designing.  It was a completely original design from start to finish including a 'drop in lid' and cosiderable rafting which needed to be removed in stages.   The lid and the box were printed separately due to their size.  There was inspiration from this box.
Size: the base was 15cm wide, 10cm across with a depth of 5cm.  The lid was essentially slightly smaller than this so it could drop down into the base.  
Above Viewed from above the compartment visible
Timeframe: Due to its size being slightly smaller than the Ultimaker 2 build plate both major pieces were printed separately.  The lid was printed in an six and a half hour print.   The box was more detailed and required ten hours.
Process: Inspiration came from another student in the classroom with thier 'Mothers Box Design'.  There were elements of that design in this, such as the drop in lid.  The student has previously used Tinkercad to produce basic classroom designs and was looking to stretch himself with a more complex design that would also have a practical use.  
What would we do differently: There was not a a signature/name built as part of the design which is something that could have been included.   The student spoke afterwards and it was suggested that there could have been an insert designed into the box that would have allowed a charger cord to have been plugged directly into the box or a dock option to hold it.  The student himself was extremely pleased with the project and the execution of it.
