NEMA17 Wheel Motor Hanger
Part of the 'NEMA17 Self-Balancing Robot Frame' kit (print ×2). This gusseted L-bracket hangs a NEMA17 stepper under the 120 x 80 mm base deck with the shaft pointing out toward the wheel. It has a 5 mm face plate with a 22.5 mm pilot hole and 3.4 mm holes on the 31 mm square for M3x8 screws. The 35 x 56 mm top flange has four 3.4 mm holes on the deck's 10 mm grid (x = 30/50, y = ±10) for M3x12 screws, washers and nuts. Round holes, not the slots many bought L-brackets use, so the motor can't shift under balancing loads.
