I designed this for the Cheng Liang P360W24V power supply, commonly offered with Creality's Ender 3 printers, for a stand-alone mount off the printer. It should fit other 'thick as a brick' printer power supplies of similar design. Print Settings

Notes:
Suggested bed placement is the legs on their sides and the bottom of the center bracket lying on the bed. Supports for the holes may or may not be needed, depending on how your printer handles bridging over holes. If you're slicing with the Cura app, tree supports would greatly help if needed.
The holes in the center bracket are designed to allow an M4x12 machine screw to slide through. The holes in the legs are just deep enough for this size screw and will be a tight fit, so take your time and don't over-tighten as you cut threads with the screw. Of course you can use an M4x1.0 tap if you've got one. Alternately, you can skip using mechanical fasteners and glue the assembly together. Epoxy, cyanoacrylate, and any other glue or solvent designed for plastic will make a permanent connection.
I used PETG, what I use for all my functional designs. Any non-flexible filament will work. Be mindful of shrinkage variance in the other filaments since my design was tailored for PETG.
