approximate size and shape) is that the plastic be flexible. As you tighten the screw against the
body of the motor, you want the plastic to deform, in order to hold the motor in place.
Another approach to homemade motor brackets is to use small
cable management clamps. The Pololu micro motors used in the
G PlastoBot fit snugly in 1/2″ clamps. You need two, positioned
opposite one another to hold the motor in place. The clamp
around the gearbox secures the motor in place, and the clamp
around the body keeps the motor from shifting around on the
base.
