Completed Project: Ooshie Stand

 

Those of you who are regular visitors to this blog while have been following the progress of the five tier 'Ooshie Stand'.   This has been sourced from Thingiverse.   To hold the entire run of the designs each level consists of eight holding spots - five levels allowed the entire run of forty designs to be displayed.

The decision has been made to spray paint the entire design in a single colour (which is purple as shown left).   The design was completed as noted in stages and each section was able to be screwed into the section above it.

This allowed the design to be put together successfully for a price point of under $10.00.   It also has the bonus of allowing the forty different characters to be transported without them falling off the design as each is held in place by an individual peg.

This is another example of using a pre-made design or feature and creating a interest and design for discussion and sharing with adults and also students.

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.

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.

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 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.

Ooshie Stand: Personalised Example

 

Challenge: To produce a personalised stand for Ooshies or Lego Mini Figures.

Background: This is the follow up from yesterdays post with the generation of ideas follow up.   We are continuing to explore further developments and ideas but to encourage the students with their designs we wanted to print a physical example that could then be used to review the ideas and consider what refinements might be required or considered.   As noted in the post yesterday this was intended for one of two things as a personalised display stand - the scale of which in theory would allow a range of the figures to be displayed.

The figures in the range were measured prior to the construction of the stand - however there is a subtle variation in the size of a lot of the figures and some have arms and other features that stick out from the base meaning that a universal stand needs to take thins into account.  In this example here the student made a slight design error that the last bay, the one with the second star is not the same dimensions of the other three and finding a character to fit in it is going to be one of the issues that the students will need to resolve.  In the example that was used with the run of twenty figures a peg has been introduced for each figure to be held in place.  In this student example the student opted to have a small division between the figures with the name of the person and the stars on either side.

This was done by applying simple fonts and also including the two 'stars' either side to ensure that there was balance and not blank sections of the design.

Finally we are always looking at considerations towards rafting or waste of plastic - there was the underneath of the design here.  A much better option for the student would have been to print the feet of the stand separately so they could glue them to the base post printing so that there would be no need for support - which essentially was nearly half the print.

Resources used to complete this print: Tinkercad App, student iPad, Bambu H2D, Blue PLA.

Level of Difficulty: Medium all of the skills that the student needed to complete the print they possessed and one would anticipate with the refinements and adjustments that they are going to make the print will be successful.

Size: The print currently measures 170mm long is 35mm wide and is currently on four feet that are 10mm high each.   The sections of the print are currently 35mm by 35mm - this will need to be revised, except for the last bay which is 25mm by 35mm and is too small for anything except for the smallest of the Ooshies.

Cost/Price: This print as it stands now uses 35g of PLA to complete the print which has a price point currently of $0.75.   As noted this could be reduced significantly by altering the underside of the print and printing the legs as seperate pieces as the weight of the objects being placed on them is minimal.

Timeframe: Two hours and ten minutes to complete (again as stated if we changed the base it would also halve the total print time.

What we would do differently/Next steps for the students - these have been more or less addressed in the additional information in the print which would affect the output.
