Captive Sphere Bearing for Fidgets

thingiverse

This is a printable alternative bearing for fidget spinners that functions seamlessly as a drop-in replacement for skateboard bearings. It feels incredibly satisfying to use. I have included the OpenSCAD code I was working with to make this, but unfortunately it seems like I lost my final revisions along the way, so the code generates a different grip than the one uploaded here. The .stl file you see is actually my preferred version of this bearing, although it's not necessarily the absolute best possible design - I stopped iterating once it felt 'good enough'.
