This file contains left and right motor mounts useful for fastening commonly-available, yellow, TT gear motors to a platform or a simple robot.
Fit the nub on the end of the gear motor into the small rectangular hole in the mount, and pivot the motor to align the motor mounting holes with the holes in the V-groove part of the mount. Fasten the motor to the mount using M2.5 X 25mm or #4-40 X 1" machine screws and nuts. Fasten the mount to your robot or platform using #4 screws in the two round holes in the rectangular section.
