Nema 14 bracket mount for flat surfaces

I made this to enable a easy 2 hole mount for a plate or a bar in order to minimize the amount of holes through the fastening plate and allow for two easy drills only. Suitable for aluminium fitting etc . The holes are un tapered , i would not put inserts on the motor as a motor amount allows for pretty much basic screws and no movement . If you print it in pla , perhaps inserts on the outer holes is good to use but since it is 10mm thick a regular washer on the screws should be sufficient.

This allow easy mount without needing to drill the recess of nema:s and for sound dampening it also benefits. The motor holes is sunk for a insex head /flat surface but also coned m3 fits well. I would suggest an infill of at least 20% as it is a mechanical part, but it shall only allow for accommodating mount so you do not need 100% infill on this one.
