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.

3D Printing: Ooshies and Maze Development

We are continuing to develop our range of Ooshie stands.   We've produced some larger scale stands and also some smaller ones such as the one shown left.

The smaller versions shown left suits two of the figures standing on a basic platform - the potential is for some degree of personalisation.

The stand previously featured in a post on the blog and since then the student has revisited and reconfigured the design - adjusting the name of the person that is on display and correcting some of the division aspects of the stand.

We printed the stand in a lime green version - we want to introduce some differentiation with the height of the stand and variation that it provides and also significant reducing the print time associated with this design.

Our 'Maze' challenge which was created by the example shown yesterday on the blog has led to the classroom working on their own versions and problem solving.

Our first step in the process is the creation followed by AR/VR project onto different surfaces to compare designs and creations - thinking critically about what might work, what needs to be adjusted and what we could do differently.   We are going to then choose as a class some of the best examples and print them and then provide physical examples for the students to test and experiment which should then again refine their designs.

3D Printed Mini Maze - Junior Designed

 

Challenge: Students to create a unique print that has a moveable parts.

Background: This print was part of the challenge that was put the students in the classroom - could they they produce something that involved movement.   In previous examples from this range they utilised cogs and stands to allow the objects to be turned.

In this example the student wanted to create a small or short mini maze that would have a ball that would be manipulated by the person holding the activity.   There were elements introduced into the maze to increase the level of difficulty.

We have previously explained how we have created larger scale versions of these in the past - including Mr Bloor's amazing Star Wars Tilt table located here.

This print is an early attempt and it is anticipated that with testing and developing ideas that a variety of modifications will be made for this activity.

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

Level of Difficulty: Medium - in the example here the student has created several obstacles- however the example will be developed and in doing so the difficulty is potentially increased.

Size: The print at present measures 120mm across and is 90mm high.   The sides of the maze are 20mm high and the sides are 3mm thick.   The two 3D Printed balls are 20mm across.

Cost/Price: To complete this print the printer used 54g of PLA to complete the print.  This has a price point of $10.7 to complete the print.   This includes the two balls used to navigate the maze.   The student is going to attempt to complete the maze with a variety of objects - marbles and small rubber 'bouncy' balls.

Timeframe: This print was completed on the Bambu P1P machine.  To complete the print it took one hour and thirty eight minutes.

What we would do differently/Next steps to the students:  The first prototype for the students is designed to inspire and encourage the students to create their own versions or develop this version sooner when feedback is provided.   There is also potential for personalisation on the outside of the maze.   The biggest part of the design will come in the form of the engineering of different challenges to complete the maze.   This will be probably determined by opening up the idea to the classroom and see what the students can design or work into this print.     

H2D Comparison Vs. P1S Comparsion

 

We've spoken recently about using the different machines that are available for our students to use.   Recently we completed a run of prints that were for a local sports teams prize giving when we produced unique and individualised trophies for each members of the sports team.

In the photograph shown left the two prints are produced by two different machines.   The larger Bambu H2D produced the print on the right, the left hand print was completed on the P1P Bambu Printer.

The two machines have a considerable price point difference - where the difference between the prints is negligible if you didn't know which print had been printed if would nearly be impossible to tell.   The timeframe is nearly identical and the finish is essentially the same.    If someone was spending money on the machines either would work for a context of the projects on this blog - however the capital output on the machines is considerably different.
