Use 3D printing to make something Accessible (Due 10/16)

The goal of this assignment is for you to develop basic familiarity with OpenSCAD. Your goal is to create a model of something that makes something more accessible for you or someone else. To keep this problem within reason for a first assignment, you should focus on things that are fairly simple to model. You should work in pairs on this assignment.

Examples would be a tactile label for something (such as a luggage tag), a guide (to make moving something along a path easier) or a lever (to make rotating something easier.

  • Your solution should be correctly sized (i.e. try to measure the thing you are modifying and to make sure that your printed object is appropriately sized).
  • You should use a simple method to attach things such as a zip-tie (simply requires small holes), or glue.
  • Your object should be small (be printable in 20 minutes to 2 hours)

You should create a Thingiverse “thing” which represents your object with a picture of your final object in use, your OpenSCAD file, and a picture of your model, along with a brief explanation of what problem it solves, how to correctly size it, how it attaches to or interacts with the real world. If you remixed something else on Thingiverse be sure to correctly attribute it (by creating a remix).

You should submit the link to your Thingiverse “thing” on Canvas.

You should also print it out to demo in class. Here is a page with information about using the Ultimaker printers. This slide deck about 3D printing also has lots of in.

The grading rubric for this assignment is as follows. When points are 1 or 0, this is pass fail (no nuance). When points are 0-3, use the following scale: 0 – Not done; 1 – Short shallow solution; 2 – Good solution; 3 – Outstanding solution.

Points Description Comments (by grader)
0-3 Create a 3D model that solves a problem
1 or 0Learn how to correctly size a model
1 or 0Apply an appropriate attachment method
1 or 0Learn the pipeline: Create a 3D printed object from your model
0-3Describe how a model should be used
