Bicycle Brake Rotor Clock

Bicycle Brake Rotor Clock
Universal!

Purpose
Designed to repurpose a broken clock face and countless worn rotors from the local bike co-op. This Bicycle Brake Rotor Clock can mount to any type of cheap quartz clock mechanism (with an 8mm central core) and any diameter brake rotor (with 6-bolt with 44mm BCD, no centerlock), and can be stood on any flat surface, whether that be a high shelf or a desktop. The adapter plate secures to the clock body and to any brake rotor of your choice with the included studs, while the rotor rests at a slight angle on the stand. The rotor pictured is an Avid 185mm rotor, chosen because it has 12 arms :)

Details
Designed using Autodesk Inventor
Sliced using Creality Print 7.0
Printed with 1.75mm eSun ePLA+HiSpeed in black, costs around 12.7g, without supports necessary

Notes

First iteration of the clock, and it works and looks slick! I had to print the studs because the actual rotor bolts are too long and will hit the clock body/casing
