Prusa i3 MK2/MK3 PSU Cover for Meanwell PSU

thingiverse

This is a PSU cover for the Meanwell/typical Chinese PSU for Prusa i3 MK2 and MK3.. My aim was to keep the appearance of the original Prusa part and for it to fit well and I think I managed that quite well. There are two versions. One for the original Prusa power button and socket, and one for your typical Chinese combined power button and socket. Please note that I have not tested the PSU cover for the original Prusa power button and socket, but the measurements are the same as the original PSU cover, so it should fit. To fit the PSU cover to the MK2 frame you have to print out the modified PSU-Y-part. Since the holes in the PSU facing the frame have different spacing on the Meanwell PSU than on the original Prusa one, only the lower hole is attached to the frame. This will probably work just fine, but I have made a jig that attaches to the upper hole so that you can easily drill a new hole in the frame in the right place like I have. 2020-05-15: I remade the nut traps for the socket to hold the nuts better so they are stuck in place while screwing on the socket, and made an opening for cables in the bottom of the PSU cover.
