This replaces the acrylic PSU bracket on my cheap open air 2020 test bench case. The acrylic broke while I was carrying it. I designed this to be super rigid so that it won't break. This is way overdesigned. I iterated using the ATX specification, but it turns out that the stickers on Corsair power supplies are about 0.35 mm on either side. This will at least fit a CX650M and smoothly slide in. The holes are sized for M4 screws. With my T-nuts I needed 10mm. You'll need longer 6-32 screws than come with most PSUs.
If you print it back face down it shouldn't require any supports.
I'm new to SolveSolid, but I tried to make it easily modifiable. I'm including native file for it, STL and STEP.
Warning: In Orcaslicer, the STEP file generates a lot of non-manifold regions. Make sure to click "repair" if you import using that.
