I designed those brackets to fix my snapmaker 2.0 power supply (PSU) on the underside of the table where my snapmaker is located.
You need to print two of them to mount a PSU.
Prints without supports (but use an inner and outer brim if printed in ASA or other warping materials).
I printed them in ASA for stability and heat resistance (although the PSU never got this hot).
Use large washers (max. 16mm outer diameter) and 4mm diameter screws. Check the screw head fits under the PSU if mounted. Screws are invisible if mounted (hidden by the PSU).
Mounting instructions (see attached sketch):
Have fun!
