Prusa i3 MK2/MK3 PSU Cover for Meanwell PSU

thingiverse

This is a custom PSU cover designed specifically for the Meanwell/typical Chinese PSU used on Prusa i3 MK2 and MK3 printers. My primary goal was to create a cover that replicates the original Prusa part's appearance while ensuring a perfect fit. I'm pleased with how well I achieved this objective. There are two variations of the PSU cover available, one tailored for the standard Chinese combined power button and socket, and another designed specifically for the original Prusa power button and socket. Please note that, although I haven't personally tested the cover for the original Prusa setup, its measurements match those of the original PSU cover, so it should fit properly. To attach the PSU cover to a MK2 frame, you'll need to print out the modified PSU-Y-part. Due to the Meanwell PSU's different hole spacing compared to the original Prusa one, only the lower hole is attached to the frame. However, I've created a jig that secures to the upper hole, allowing you to easily drill a new hole in the correct position. On May 15th, 2020, I revised the design by adding improved nut traps for the socket and introducing an opening at the bottom of the PSU cover for cable management.
