3D Printed Miniature Storage

 

Challenge: For an eight year old student with limited Tinkercad ability to produce something personalised and unique.

Background: As per the description this student has had some experience in using Tinkercad, in the class this year as part of the new cohort of classroom students.  The students prior to the School Holidays were given the option of producing something personalised and unique which they were tasked with designing in their own time.

This student wanted to make something as a gift for another member of their family.  They used their iPad and the Tinkercad app to project the image onto their desk in the classroom to check its viability.   Following this process the design was then submitted to the classroom teacher for printing.  The teacher responsibility was to insert the file for printing.

When it was printed the decision was made to use the silk eSun multi-coloured PLA to create something of an affect with the printing process.

Resources used to complete this print: iPad, Tinkercad App,, eSun Silk Multicoloured, Bambu H2D.

Level of Difficulty: Low - this is a basic design that the student was able to produce confidently by themselves.  This is a variation of a basic design that the student was able to manipulate to expand the design.  Design basics like making the name inserting it into the back of the design as a hole instead of extending out are design features that really add depth and finish to the students 3D designs.

Size: The print measures 80mm across and was 40mm wide and the print extends a further 30mm at the back.  The print in general has a width of 5mm.

Cost/Price: The print is miniature in scale.  It used 28g of PLA to complete the print.  This gave the print a price point of $0.70c to produce the item.

Timeframe: The print had a total completion time of 53 minutes in total.  This included 47 minutes of printing time for the project and six minutes of warm up time for the machine.

What we would do differently/Next steps for the students:   This unit was produced in miniature and could be potentially expanded larger to scale.  The front of the design currently is essentially blank but could have had another picture, image or writing included (as per the top picture0.   At this stage the student felt that this would be an excellent jewellery box.   We have a range of previous designs - an exemplar of note from 2017.  In addition you can search the blog with our eleven years of examples by using some keywords in the top right hand corner of this blog.  We have tried to tag prints as accurately as possible.

3D Printed Box - Additional Features

Above: Box shown from above

Challenge: To produce a personalised box as a gift that is able to be used as a storage box.
Background: Student had produced a series of basic prints, and was looking at producing a gift for a family member.  She wanted to personalise the box with the name of the person it was intended for. 
Level of Difficulty: Medium.  Tinkercad interface was used to produce the box shape.   Student added additional features to the box to divide it into different areas and experimented with adding the hexagonal featured storage shape shown in the photograph.   The personalisation of the box took the form of lettering that was sunk into two sides of the base of the box - which was not successful. (see below). 
Timeframe: Eight hours.    The width of the sides (see below) should have been increased to provide more strength and depth to the sides of the box.  The student ultimately decided not to produce a lid for this box as they wanted the box to be a stand alone design. 
Size:  8cm long by 9cm high.  The box was 5cm high.  The external wall of the box was 5mm.   The internal walls (shown in illustrations) were thinned to 1-2mm.

Above: Front of box was deep lettering

What we would do differently: The internal walls were too thin.  At 2mm they were not strong enough.  While they have not yet broken the strength is clearly not there in basic testing.  In addition at two points the internal wall stops short of touching the main external wall.  This was created by student Tinkering.  The lettering on the external side of the box was not successful.   The name of the gift for the student ('Simone') was sunk deep into the base, when it was removed not all the materail could be successfully taken out, and the lettering itself was damaged.   With the 'Love Georgia' inscription as shown clearly in the photograph above most of the filament rafting was removed easily, however there was filament that could not be removed as requires an additional tool to do so.  The reverse side, shown below, when the rafting was carefully removed by the student resulted in damage to the font and the lettering.   The lettering in this case was sunk too deep into the base of the box and lacked enough robust support for it to be shaped successfully.
Next steps for the student: As mentioned in previous prints the design/ideas and format for boxes has been nearly exhausted by the students/classrooms efforts.   Students (in this case a ten year old) have produced a variety of boxes and details of which have been increasingly detailed and complicated. 

     

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 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.
