Mini Bearing Keychain

This is a "Mini Bearing Keychain" for anyone who wants a interesting looking keychain! I'm still experimenting with how to design supports to build components within another component so if you have any suggestions of how to further improve the design do let me know!

Dimensions:
Bearing outer diameter - 53mm
Bearing inner diameter - 16mm
Bearing ball bearing diameter - 5.4mm

Its a good gift for those who are interested in bearings.

Cheers and enjoy!
