N20 Gearmotor Tunnel Clamp
A 24 x 26 x 22 mm block that holds one N20 micro gearmotor under the chassis, for the 'N20 4WD Skid-Steer Rover Base' kit (print 4). The gearbox slides into a 12.4 x 10.4 mm open-ended tunnel with 1 mm lead-in chamfers, and an M3x6 pusher screw in a 4.0 mm heat-set insert clamps it in place. Two M3 heat-set bores (4.0 x 6 mm, 16 mm apart) take M3x8 screws from the plate top.
