This ball caster was originally released as a replacement part for the 3pi robot, but the 1/2″ ball can also be used a replacement part for the newer 3pi+ robot, which has the housing for the ball built directly into the chassis. This ball caster can also be used as a general-purpose ball caster: when mounted through a hole in a chassis that uses our micro metal gearmotors and our 32×7mm wheels, as on the 3pi, this ball caster is just the right height to keep the chassis level. The hole for this ball caster in the 3pi chassis has a diameter of 600 mils (0.6″) and has a side that is flattened by 30 mils (0.03″).

To replace the ball on your 3pi+ robot, simply pop the existing one out of the socket on the chassis and pop the ball included with this product in instead.
