Motorbike keyring with working wheels

Super simple and easy to print motorbike keyring with working wheels.

You'll need 2x 608 bearings to complete the assembly. They're the bearings found in skateboard and rollerblade (inline skate) wheels.

To avoid snap fit clips I designed the keyring such that the wheels are assembled by pausing the print when the axles are long and slipping the bearings onto them (of course, you need to have printed the tyres and pushed them onto the bearings first).
