2020 Axial Stepper Mount

A simple bracket for mounting a NEMA 17 stepper motor and filament extruder assembly to the top rail of the Ender-3, or really to any standard 2020 profile rail. This particular design holds the weight of the stepper centered, directly beneath the rail and allows you to mount the extruder in convenient front-facing orientation.

I can vouch for their structural integrity, these have held my steppers on my Ender-3 for roughly 3 years and despite being PLA have not deformed.

Installation requires 2xM4/6mm bolts and any T-nut. I just printed these so I don't have to buy special hardware: https://www.thingiverse.com/thing:5155562
