Mk2 of my ATX PSU cabinet. This one should be easier to print than the single piece version. Just print out one of each piece (choose one right hand side panel) and use a bajillion 3mm flat head screws to assemble. Fans mounted to the rear of the power supply, old school style, work with the solid right side. PSUs that have the 120mm fan in the bottom should use the louvered right side panel so the fan can breathe. Any cabinet over 110mm deep will cover the open top of this one. I designed it to have my Raspberry Pi case with ATX input mounted directly above but anything could be of course.

I printed out the rear piece this morning with 2 perimeters, alternating extra wall, and 20% infil. Seems plenty strong enough. I'll probably use those settings for the rest of the pieces too.
► Uploaded another right side panel with louvers for use with PSUs that have the fan in the bottom. Some of the louvers will be blocked if you use the standard rack, my 180mm deep rack will clear them.
►01/22 Updated the back piece. Screw holes were just a little off. If you already printed the first version a small file can easily fix the misalignment. That's all I'm doing with mine, I just fixed for everybody else.
►01/23 No part changes this time. Just an update. I've got the back, bottom, and two sides printed. I had to get some 6-32 x 3/8" screws to attach the PSU to the case since the mounting flange is much thicker than a sheetmetal PC case. These should be easy to find. Otherwise those parts printed nicely and fit together fine with M3x10mm flat head screws. Only parts left for me to test are the top and face panel, so far no issues, everything fits good, PSU is held securely.
