I needed a mounting solution for a Meanwell ERPF 400 24 PSU, for my Ender 3.

I chose DIN mounting for as cleaner setup but lacking a ready made plate or even screw holes on the PSU case, I drew one up from scratch.

There are 2 versions - v1, the prototype - currently mounted on the E3 and v2 - the close refinement - not yet mounted, I'll do it in probably a couple of months.

The V1 is meant to take M3 heat inserts and also it's meant to works with DIN Rail Bracket - Heat Insert Version - 62.5mm - DIN Rail Bracket - Heat Insert Version - 52.5mm & 62.5mm by mmuellerphoto | Download free STL model | Printables.com.

V2 is built on the same principle.

Both mount to the bracket with M3x15mm screws - pictures.

V1 is not meant for the printer to be upside down.

V2 could manage that since it's tailored with a top brace securing the PSU to the plate.

The brace is meant to take 4 M3x10 mm countersunk screws - directly to the plastic, no inserts.

Print specs - these should be tailored to your printer, below you find mine:

Material - PETG

Nozzle - .4 brass

Layer height - .16

Layer width .4
