Prusa i3 MK3 PSU cover with rear power input

This is a PSU cover for Prusa i3 MK3 (and MK3S) that has the power input on the back.

I recommend that you completely remove the PSU from your printer (including all the wires!) before attempting to install this cover. I did it with all the wires still zip tied to the printer and it was such a pain.

The power panic board still fits in this cover.

This cover works with the standard rubber feet.

You will only need 1x countersunk M3 bolt and 1x M3 square nut.

Print the "wire gap" version if you would like to make installation a little bit easier.

STEP file included for easier remixes.

Print instructions

These models should work with a variety of print settings. I used:

.20 layers
no supports
oriented as shown in the .stl's

PETG or ABS for heat resistance.
