Ender 3 All-in-one External Electronics Case

This is an external electronics case that houses 2 buck converters, a 5V relay, a raspberry pi, the printer power supply, and any Ender 3 main board or drop-in replacement board such as the BTT SKR Mini E3's.
*Power supply mounting solution only tested with a Meanwell power supply that comes with Ender 3 pro and Ender 3 v2. Regular Ender 3 and other PSU's may work also but I have not tested or been able to find drawings of them.

This was designed for mounting on the outside of a 3D printer enclosure, so the electronics do not overheat inside the enclosure. There are no mounting holes for this electronics case because many people have different types of enclosures. You can set it on top or you can drill holes through the bottom and screw it to the side of your enclosure like I did.
