Gearmotor Dimensions:

The face plate has six mounting holes evenly spaced around the outer edge threaded for M3 screws. These mounting holes form a regular hexagon and the centers of neighboring holes are 15.5 mm apart. Additionally, unlike our other metal gearmotors, this unit has an output shaft that has a diameter of 6 mm rather than 3 mm.
