Print-In-Place Omni Wheel 5 mm Shaft
A 65 mm diameter, 20 mm tall omnidirectional drive wheel that prints in one piece with six free-spinning barrel rollers already captured on 4 mm pins (5.1 mm bores, 0.5 mm clearances — no assembly, no hardware for the rollers). The 5.3 mm hub bore is a slip fit on any 5 mm motor shaft (NEMA 17, 37 mm gearmotor, N20 output) and locks with an M3 set screw into a captured M3 hex nut, giving a hobby robot a holonomic/kiwi drive base without buying imported omni wheels.
