Bearing Cube (Fidget Cube)

thingiverse

I'm excited to create a model showcasing bearings and tolerances, so I decided to design this little cube. The cube is intended for use with Spitfire Cheapshots skateboard bearings, making it likely that other bearings will fit just as well. However, the fit of the bearings in the cube can sometimes be loose, allowing me to simply shim the bearing into place using a piece of support material and ensuring a snug fit even when spun at high speeds. The center caps generally fit nicely too, although I can also shim them for an even tighter seal. Overall, this model is pleasantly weighted and spins smoothly. I printed it on my Monoprice maker select v2 with the settings below and was pleased with the results after minimal sanding. This is my first project in FreeCAD and the first thing I've uploaded, so please let me know what needs improvement and I'll release a second version. I added the .fcstd file and it would be great if someone more familiar with FreeCAD could review my standards and suggest better practices I could use.
