Replacement 3pi Ball Caster with 1/2" Plastic Ball


Vendor's Description: 

This ball caster can be used as a replacement 3pi robot part or 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.
