Nema 17 Motor Mounting Bracket

thingiverse

This is a 10 series 8020 extruded aluminum mounting bracket for Nema 17 motors. Aside from the 4 holes for mounting the motor, there are holes for 6 M3 machine screws to act as structural support against loads normal to the layer lines. These also prevents layer splitting caused by the clamping force of the bolts holding the bracket to the 8020. Recommend 100% infill. Hardware used: 4 x 8 mm M3 machine screws to mount the motor (or 10 mm) 4 x 0.5 in 1/4-20 machine screws 4 x 1/4-20 tee nuts 6 x 30 mm M3 machine screws and nuts Note: For the structural support screws, I use 6 x 30 mm M3 machine screws and nuts, but 1 1/4 inch 6-32 machines screws and nuts should work as well Also note: you can use shorter (20 mm) length screws for two of the holes.
