Tight Better Simple Gyro Keychain

I like the Simple Gyro Keychain by Jangles1981.
But it has a little design error causing the outermost ring to stuck.
I redesigned this so the gaps are real spheres. Unlukily they have not real smooth surfaces because i was using tinkercad.

This is the tighter version that works better. If you print this and the rings stick together you should try my other version.

Have Fun!
