Print-In-Place 60 mm V-Race Caster Wheel
This 60 mm OD x 20 mm wide replacement caster wheel prints in place, with the tire spinning around a separate captive hub on a 45° V-ridge race. It suits office chairs, rolling coolers, carts and luggage. The hub has an 8.3 mm bore, so it slips onto the original 8 mm steel axle pin. The hub's raised 16 mm boss acts as a fork spacer. Wear lands on the large 34 mm race instead of chewing out a small axle bore.
