Upload of my work from 2018.
Now that I'm getting serious with my fidget printing again, it makes sense to have all my models in one place. :)

This is a printable alternative bearing for fidget spinners.
It feels really good!


Designed to enable more wacky zero-assembly 3DP fidgets!
Confirmed fun!
Designed to function as a drop-in replacement for metal bearings (skateboard bearings) {22mm diameter, 7mm thick} 

I have included the OpenSCAD code I was working with to make this. It looks like I lost my final final revisions, so the code generates a different grip right now than the .stl here. The uploaded stl is my favourite version of this bearing, but not the best possible - I stopped iterating once it felt 'right enough'.
