3D Printed 'Cyclops' Challenge: Masterclass

 

Challenge: Given a toy eye the students in the classroom were told to create a build/project around it.

Background: This is the finished version of the first initial print.  The process behind the design for this print was detailed in a previous print on this blog.

This design is now shown with the eye firmly in place - without glue as the student was able to force it into the eye socket when it then expanded into place, held there by the design.    The design is used to hold a USB flash drive.

At the same time that this was being produced one of the other students wanted to create something on a more significant scale.   This student is a eight year old student who has shown creativity and aptitude with her designing work and skills.  She wanted to use a 'cyclops' theme to produce a unique storage location.   Tinkercad was used as the main design tool.

The design is shown left on the Tinkercad design page.    The student opted for a single eyeball which as shown was on a stalk, with two pods of storage either side of the main body.

Level of Difficulty: Medium - the design has a number of aspects and details in it.   For instance the spikes on the body and the boils have been created by adding small cones and circles at different locations and then flattened out or added.     The balance with the design was required and it also needed to work with the scale.

Size: This was a significant print in terms of size.    The print measured 170mm across and was 90mm wide.    The main height of the body of the print was 120mm.   The Pods were 70mm long etc.    This was intended as a significant print.    The stalk with the eye in the middle was a further 70mm high.

Timeframe: This print took four and a half hours and took place on the Bambu H2D Printer.   This made sense with the dimensions and also the details that we wanted to bring to the print.   There was absolutely minimal rafting that was produced with this print - if we had used our other primary machines, the Snapmaker then we would have expected significant rafting with this projects.

What we would do differently/Next steps for the students: 

The student has shown the ability to be able to produce prints such as this.   When the initial challenge was set to the students they were asked to incorporate an eyeball into it this student opted to move in another direction.    The student could have looked to use this with the design, as they could have opted to use the printer to change it colour.

The student could have looked for additional features and develop the design further.   While they put a considerable amount of additional features onto the design but they could have added further details.

We have used the 'monster' theme numerous times in the classroom as a design focus because it allows the students to not follow particular rules or details (such as when a cat is designed) 

3D Printed Junior 'Cyclops' Challenge

Challenge: To use a large single eye in conjunction with a print design (aka the cyclops challenge).

Background: We are nearly three quarters of the year through the school year in New Zealand and the students have been using Tinkercad as a design tool for nearly all of this time (as we started projects in the first week) there is also a number of students who were in the classroom last year with nearly two years design experience.   As a teacher I tend to be looking for examples and ideas that I can present to the students, the classroom and challenge them to come up with ideas and creations with a loose direction.

This project idea came from something that developed with a previous print project on this blog.    We were using a 'cat' theme for our literacy tasks and so a natural fit was 3D design - the students finished several of these designs with stick on eyes - as can be seen in these posts on this blog.    While we now have the potential to use the Bambu H2D to change filaments mid print and produce a eyeball we also wanted to look at a physical 'eye' as a starting point for a design.

By purchasing a packet of large oversized eyes from a local craft shop, for a nominal fee, it was presented to the students with the challenge of producing something based on the design however the students could only have one eye and the print had to have a purpose to it.    The students brainstormed ideas and looked into projects that had worked previously from storage to pencil toppers.    The limit to the eyes created a 'cyclops' aspect to the challenge and students worked in monster designs as part of it.   As shown left and above the student used the Tinkercad main interface to design oversized teeth and gums, ears and a socket for the eye.

The students were collectively creating as so were able to bounce ideas off each other they also used AR/VR to project their designs into different locations to look at their suitability for design and to consider aspects of their creations.   In the example shown below the student duplicated his original design.

This allowed him to develop two seperate prints for his project, a pencil holder on the left, which he then inverted and turned into a pencil topper, reduced the size and put a hole in the bottom so essentially turned one project into two.   

Level of Difficulty: Low - this is essentially a task where the open aspect of it allows students to create something with an open scale and design features (for instance it would have been more challenging to produce a realistic cat.

Size: This print was initially created to be 70mm across and was 60mm high.   The print was designed originally as a prototype and to realistically store pencils would need to be of a larger scale, with greater ability to hold stationary.   The pencil topper needed to the other direction as it couldn't be too big as it would upset the ability to write realistically with a pencil.

Timeframe: Just over two hours.  This was completed on the Snapmaker printer - if it had been completed on the Bambu we would have expected this to be half the time, something in the region of one hour.

What we would do differently/next steps for the students: As noted there is some redesign that is required when the student decides on the direction that they want to go on, either increasing the storage or reducing the storage depending on the purpose.   The design is robust, comical and the student has the balance right between the task and producing something that has appeal.   The other thing to keep in mind is that the student who is responsible for this design is seven years old, although they have shown an aptitude for creation and design.
