2x2x2 Rubik's Cube

I was surprised I couldn't find a working 2x2x2 Cube on Thingiverse so when I found a cheap rip-off I sat down and here's my first attempt at making a 2x2x2 Rubik's Cube in FreeCAD. Print one base, 3 center caps, 7 corner stones and 9 inner sides. See pictures for assembly instructions.

You'll need three M3x16 bolts/screws to attach the center caps to the base. The Cube I inspected/disassembled for this design had springs to pre-load the center caps.
