This wheel is designed to fit securely on the 3mm output shafts of our 12mm micro and mini metal gearmotors and the Pololu 120:1 mini plastic gearmotor 90-degree 3mm D-shaft output. These are the same wheels that are used on the Pololu 3pi robot.

Both our micro metal gearmotor bracket and extended micro metal gearmotor bracket work with this wheel.
