Ender 3 Improved Power Supply Cover

thingiverse

Improved cover for the Ender 3 Power supply. Improvements over the factory cover: * Power socket and switch moved to rear of machine, so the IEC plug doesn't awkwardly stick out the side * Position of opening for XT60 DC power connector moved to the front, so the cable tucks neatly along the crossbar * Physical Separation between AC Mains and DC terminals and wiring * Has a cutout, so that it does not obstruct ventilation slots * Optional cutouts for Mains switch and DC switch on side, suitable for 13mmx19mm snap in rocker switches * Slighly larger internal volume, giving you so much more room for activities You can reuse the hardware which was included with the factory cover including the original IEC socket with switch. I printed mine in PLA with 1mm walls (so it is essentially solid) and it has held up very well. However I had fillets in the front corners, so the side screw didn't line up. That issue should be fixed in this version. Note this is not suitable for the thinner Meanwell supply which ships with Ender-3 Pro. You will likely need supports at least for the IEC extrusion at the rear. Also if you set them up right, you will have nice breakouts for the switch cutouts which you can leave intact until you are ready to install switches in these positions.
