This is a fidget spinner shaped like a cube. It is based on the original design from Tato: https://www.kickstarter.com/projects/t8o/the-most-portable-fidget-spinner-spincube/
You will need to print 1x Cap1.stl, 1x Cap2.stl and 1x Core.stl. You will also need a skateboard bearing for the spinning mechanism.
Additionally, I have created press jigs that will allow you to much more easily assemble and disassemble the design.
Files Updated 10/17/19: The caps are not identical. In a future revision, I will make identical versions to make it a little bit easier to print/assemble.
The core will most likely require support.
