A two-wheel traction module to build whole: an N20-size micro gearmotor in its printed case and lid drives a 3 mm D axle through 90° by a pair of 8-tooth bevel gears inside the Wheel Drive Frame, and the axle carries a 16.8 mm Wheel Rim and a LEGO 30.4 × 14 tyre at each end. Every gear and rim grips its shaft with an M3 × 4 grub screw. Bolt two to a plate and you have a robot's drive train.
