Ender 3 Back Electronics Box

A very basic full width back box for the Ender 3. I built this to be as open on the inside as possible to make room for larger boards and complex electronics.

Internal mounting points are for a Duet 2 board and that is all. The rest is open to add electronics as you see fit.

There is an opening for a 40mm fan to be mounted externally and several bottom mounted vents on the other side of the case to promote airflow over the surface of the board.

If using on an Ender 3, the only wire that should need lengthening is the Z stop.
