This is a remix of External Electronics Box for Ender-3 Pro by sgsunder (https://www.printables.com/model/226631-external-electronics-box-for-ender-3-pro)

The Original files were made for Meanwell thin PSUs.

It fits ender 3 stock or skr mini boards and a raspberry pi (3b+ here)

I'v only updated the back part. On the main box I have a todo to fix the placement of the psu cooler screws. On my build iv used 1mm double sided tape. I think the fixation is better and makes the build more stable. The attached picture is for the original build.
