Ducati watch (with disc brake)

thingiverse

I decide to refurbish my oversized monster brakes, opting instead to replace them with a large garage clock that I'd picked up at a significant cost due to its expensive price tag. The bore for the hour hand measures 5.32 millimeters in diameter, while the bore for the minute hand measures 3.80 millimeters in diameter. Meanwhile, the central bore of the support itself is an impressive 8 millimeters across.
