Parametric Prusa PSU Mounting brackets

thingiverse

To address a unique issue with my 12V 20A power supply purchased on Amazon, it didn't have the standard screw holes found in other PSU mounts. I overcame this by utilizing the bottom-mounted holes on the PSU and designed a parametric OpenSCAD model to accommodate any size of PSU. This mount is positioned below the Y carriage. To install, print four or more copies of the bracket and use M3 screws with washers for each one. Turn your Prusa upside down, position the power supply beneath the Y carriage, attach the brackets to the M8 rods, then press them down and tighten the screws. Note that on my specific power supply, screwing too deeply into the unit caused issues with the Arduino; consider using nuts, washers, or nylon M3 screws to prevent this.
