Pololu's universal aluminium mounting hub, from their own CAD — what puts a wheel on a motor shaft. Twelve SKUs across six bores and three thread sizes, and every one is a distinct drawing: the tapped holes really are 1.78, 2.26 and 2.50 mm, which are the tap drills for #2-56, #4-40 and M3. The 3, 4 and 5 mm hubs are a 5 mm thick disc with four holes on a 12.7 mm circle and one set screw; the 6, 8 and 1/4″ hubs are 9.2 mm thick with six on a 19.05 mm circle and two set screws. Both circles are the ones Pololu's own wheels carry.
