N20 Gearmotor Zip-Tie V-Cradle Mount
A 48 x 34 x 20 mm chassis mount for micro metal gearmotors (N20/N30, 12 mm round can): a 90° V-cradle self-centres any can from about 10 to 14 mm diameter and two 4.5 x 2.4 mm tunnels take zip ties straight over the motor, so it needs no motor-specific bolt pattern. A 6 mm solid rear thrust wall stops the motor being pushed back by wheel side load, and the 4 mm base has four 3.4 mm M3 slots (11 mm of travel, on 30 x 25 mm centres) plus one round 3.4 mm M3 hole for a located third point.
