I've created a clock out of a motorcycle rim and a digital clock off of amazon. All parts are 3D printed to hold the clock to the rim. There is no adhesives used in this project. The rim is off of a Honda Grom Clone (Hellcat 125). The size is 2.75 x 12 Alloy rim. It's designed to be used with only the rim.

If you happen to make one please share.
I used .12 resolution for the threaded parts.
