Print you own Nema 23 motor mount. A low cost alternative to aluminium mounts and more accurate than most wooden constructions.
Nema motor mounts are usually quite expensive. The quality of the mount does very little to a CNC machine’s accuracy. So I decided to print one. It raises the motor about 2mm above ground. My motors fit snug into the mount hole.
The mount is relatively sturdy. I had a bit trouble with warping, since my heated bed didn’t work properly. Thickness of the base can be increased to improve rigidness. For the particular machine I built, 2 mm was al I could afford.
