About this 3D model

This is a cover for the back end of a round NEMA23 stepper motor from Machmo. It requires 2x #4-40 1 inch long socket head screws to attach it to the rear of the motor and accepts 1 GX16-4 connector (16mm diameter round 4-pin connector commonly available for around $1/piece on EBay). There is plenty of room to wind a little bit of extra wire inside and it will be protected from the motor shaft.
