5 mm Shaft Robot Drive Wheel
A 60 mm OD × 18 mm wide spoked drive wheel that slips onto any 5 mm motor shaft (NEMA 17, 37 mm gearmotor) and locks with an M3 set screw threaded into the 6.3 mm hub wall. The 8 mm × 2.5 mm rim groove seats a #64 rubber band as a tire, and 24 scallops in the flanges give traction if you run it bare — replaces the hub-and-tire set nobody stocks for one-off robot builds.
