3D Printed Kicking Tee V2.0

 

Challenge: To take the idea and the design of a kicking tee and adapt and modify it.

Background: This concept, idea and print exploration was previously explored on this blog in a previous post - this is the revised version of that print.

As noted we had a number of students using kicking tees for their place kicks, and a student brought one in and wanted to investigate making it into a 3D Print.  When the first prototype was completed the student was more than happy with it however there were clear opportunities to develop it further particularly with the personalisation and design.

Resources used to complete this print: iPad, Tinkercad App, Prototype, Bambu H2D, Bambu PLA Green/Lime regular PLA.

Level of Difficulty: Medium/High this requires some refinement but is something of a statement piece that is going to be quite visible moving forward.

Size:   This print is 170mm long and 120mm wide.  The print is 80mm high.

Cost Price: The original print was a 120g/$1.87 unit.  This revised version used 140g of filament which had a cost price of $2.37 - reflected in the different sizes.

Timeframe: The newer version of the print took four hours and fifty three minutes to complete.

What we would do differently/Next steps for the students:   We have already identified that this print is a prime candidate for a PETG print as we consider the potential use of the print would be something that could be struck or come into physical contact as it is kicked.

We have no concern about weather tightness however we would want to carefully observe the print where the lettering has cut out into the design.

Ooshie Stand - Complete with handle.

 

In addition to yesterdays update related to the Ooshie stand - the addition of a handle, this is the top of the design from the original file on Thingiverse.   

The handle is similar to the dimensions for each of the previous described levels of the print.

The lid used 29g of regular PLA to complete.   This print had a price point of $.45c to complete.   As mentioned with the layers taking $1.57 to complete for the entire run of the design with five layers (eight Ooshies on each level)  there are forty in total.   

This meant that the entire print has an estimated cost of $8.00

We have seen versions of this stand retailing for thirty or four dollars to complete.

Lego Non Lego Figures V2

 

Challenge: For student to create an original 'Lego Non Lego' figure.

Background: Using Tinkercad to create figures can be challenging, students at times can spend a considerable amount of time on the challenge, the concepts and the dimensions.   This was the case in this example shown left.  The student wanted to use the design features to make all of the features for a character - the student used a couple of pre-made items that they used the facials being the obvious examples.

The student also wanted to have something that might be able to be swapped out or interchangeable in this instance it was the hat - the hardhat shown in this design could be switched out and replaced. We have had a number of figures produced in this challenge from earlier in the year including examples such as this.  The relative size of the figures means printing tends to be feasible.

Resources used to complete this print: iPad, Bambu P1P, Bambu Blue PLA.

Level of Difficulty: Medium - this figure is nearly some form of completion but there is additional issues to be resolved.  

Size: The print is 80mm wide and 105mm high.  This print has a width of between 30mm and 40mm.

Price/Cost: The print in its current form uses  35g of regular PLA  to complete and this has a price point of $0.71c.

Timeframe: This print took two hours and ten minutes to complete.

What we would do differently/Next steps for the students:  As can be seen from the images left the shoulders of the print currently look very 'blocky' and need to be addressed.  The hands relatively speaking are oversize and need to be reduced.  The writing that is on the figure on the chest reads 'Auroa School construct' which is too compact it needs to be separated out or reworded.

Ooshie Stand from Thingiverse

 

We've spoken before about the use of third party location sites to provide examples and prints that we can use for inspiration or do modify.    In this example we were able to locate an 'Ooshie Stand' that was available as a free download on Thingiverse.

Our students have been designing their own version - and in this example here we printed it via our P1P Bambu Printer.

This print was printed in sections, each of the sections were able to hold eight of the figures which had a peg on which they could be mounted.    As the full range of figures is forty figures a five tier would take care of all of the figures.

There is also (not pictured) an additional cover for the top of the print and also a handle that goes to finish the file.   The sections that are featured here in the photograph each have a regular print time of three hours and forty five minutes.   The print uses 82g of PLA (regular) to complete the print which has a price point of $1.67c.     To print a stand to feature all of the figures would of course require just under ten dollars of PLA to complete the print to house forty figures.

Maze Development: Student Summary Examples

 

These screenshots from this post represent some of our students work combining the elements of Seesaw, Tinkercad (the app and its AR/VR ability) and our students iPads.

This is of course the 'Maze' activity from our students which has included the first step of creating a virtual design, providing them with feedback and then identifying improvements that can be made.   The students then had the ability to make improvements on their design, discuss with partners that they were working with and review the design and then project it again onto a variety of locations.   Students have opted to place it on different surfaces to see how it 'popped' the design and creation.

The students variation has also led them to consider a range of designs for the ball for the maze.   As we would obviously expect - not all of these designs will make it to the physical printing process.

The AR/VR work here was conducted in a single afternoon, the designs having been made the previous day and then altered or modified depending on the feedback that the students have given each other.

3D Printed Student Designed Ooshie Stand

 

Challenge: To produce an original stand that was suitable for either Ooshies or Lego mini figures.

Background: As noted previously we have a 'craze' at school amongst students - a small supermarket accessory called am "ooshie' while replicating these accurately would be very, very challenging we also looked at ways that our eight and nine year old students could use their design skills to create something to compliment these items.   The obvious thing was a stand or a way to display the items - hence our students early attempts at 'Ooshie stands'.   Having followed the process of generating ideas we have found a series of creations that we have decided to turn into physical prints.   

The criteria for doing this was based on originality of the design, the viability of the design and the impact that it was likely to have on encouraging other students to refine their ideas.   The personalisation of the task or design was a must do and this design was able to clearly demonstrate that had been understand and there was also potential for further details.    Already there has been the discussion about the back of it.

Resources used to complete this print: iPad, Tinkercad App, Ooshies (for sizing),  Bambu PLA, Lime Green regular PLA.

Level of Difficulty: Medium - this is a straight-forward design that the student who is nine years old was able to complete independently and presented to the teacher in its completed form.

Size: This was much larger than earlier versions of this design.  It measures 100mm across at the front was 50mm the stand was 130mm high.

Cost/Price: To print this stand 156g of PLA is used.   This has considerable rafting between each of the shelves.   This gives the unit a cost price according to Bambu Lab Studios of $3.13.

Timeframe: To print this stand the Bambu H2D took five hours and forty minutes to complete.  As noted if we re-engineered to print we could print each of the shelves separately - this would reduce the rafting and print time considerably.

What we would do differently/Next steps for the students: The shelves could be re-imagined or re designed using the idea to print in seperate shelves and then glue them together.   The entire back of the shelf is also another potential spot for personalisation or something like a vinyl sticker.

3D Printed Marble Maze: Junior

 

Challenge: For students to create a unique project that involves movement and engineering challenges.

Background: We have been posting about this project as it developed from a idea based around movement and morphed into a challenge for the students to develop their own marble mazes.   We have a range of designs created from student producing their own unique mazes to taking and adapting existing models, such as the one shown left.

In this example the design aspects of the project are focussed around the student creating the 'traps' for the ball, which range from a simple hole to be placed into the design to the addition of ramps and blocks which can be seen in green on the design shown left.   The student had to also consider the size of the gap between the walls of the maze and then think about a ball to run through it - would Tthey use a marble? a smaller 3D Printed ball?

Again as we have mentioned the purpose of this project is not to create a 3D Print for everyone in the classroom it is to engineer ideas and solutions to meet the design brief provided by the challenge.

Resources to complete this print: Tinkercad, Maze Template .stl file, iPad, Bambu H2D, Lime green PLA.

Level of Difficulty: Medium - obviously this maze plan has been adapted.  To create an original maze from scratch with all of the working parts would increase the difficulty level of this task significantly.

Size: The print is 190mm wide and 190mm long.  It has a height of 20mm.  The walls are 5mm thick.

Cost/Price: Despite its dimensions the print uses 190g of PLA to complete the print.  This created a price point for the print of $3.81.

Timeframe:  This print took five hours and five minutes to complete.   There was minimal rafting.

What we would do differently/Next steps for the students:  There was a small gap underneath the design between the left hand side and the edge of the design.    This was only 1mm or so wide and was not easily visible but would need to be addressed to tidy the print up.   The blocks that created the ramps served a purpose but could have been more refined.
