Summary

Parametric bracket
Openscad program

I needed a bracket to hold my Nema 23 stepper motor to a test rig.

These are the parameters I used for a Nema 23 stepper motor bracket.

thick = 2.5;
center_hole_dia=38.7;
center_hole_height_from_base=55;
width=96;
small_hole_dia=6.3;
small_hole_pitch=47.2;
fillet_rad=12;

The stepper motor fixing holes measured 5.5 mm diameter so I put a M6 Tap down the holes and bolted the motor to the bracket with M6 cap heads.

I had 2 corners curl slightly up not sure why.

If you increase the width parameter then you can increase the fillet rad to add more strength to the bracket. If you increase the fillet rad too much then the fillet may cover the holes.
You also have control of the center height from base.
For no holes just put diameter to zero.
The height of the bracket will be the same as the width i.e. square.
