Various STLs I made for various things.
This is the stock Ender 5 Plus PSU and intended to be attached to an DIN3 Rail.
This should work with many cheap PSUs, I made it specifically for this one: https://www.amazon.de/gp/product/B078B5BWDF
It intended to dangle off 2/3 of the rail. It's not ideal, but works well enough.
For a stronger part, use Generic 80 LED PSU Brackets.stl
