This is a Nema 23 Motor mount I designed for my DIY CNC Router I am building.
There are two files, on with anti-warping snap off circular pads and one without.
I find the pads help reduce warping when printing in ABS or HIPS.
The mount is 78mm long, allowing a coupling inside the mount, CNC Style.
Nov 2017 added step file.
