Planetary Gear Keychain less

thingiverse

I've always dreamed of printing bearings like this. Unfortunately, I couldn't get the print right. It always came out welded together. But this time, I was able to print the gears and ring separately, then hammer them into place later on. My last challenge was the keychain hole. I didn't want it, so I cut it off for the 100% model. When I wanted to print something bigger, this process would be more difficult, so I designed a smaller version with no keychain to use as a regular bearing regardless of how bad your printer or slicer is - like mine in my case.
