Description
The Meanwell HRPG-300-12 has a different form factor than the original Prusa power supply.
Here are STL files for my case and a parametric FreeCAD drawing that should easily adapt to different dimensions. The upper mounting hole in the printer's frame is utilized by the side_mount.stl adapter.
Note that this was designed for the older Prusa i3 MK2 with a 12V supply. The newer i3 MK3 series requires 24V.
After a few months, I found an issue with this design: There are no venting holes.
The particular meanwell unit I used has a fan on the rear end, but no other grills to let out the air... :-)
TODO: Add some vents at the bottom, but still protect the electrics well!
