This is a large enclosure for my 3D-Printer's electronics. It can house a HP DSP600 Powersupply whitch I modified to start up right away. Be sure to know your limits when working with high currents! This might be dangerous.
It also fits a Ramps1.4 Controller-Board and a Rasperry Pi 3B+ running OctoPrint.
The RaspberryPi gets Power directly from the main powersupply so only one powercord is needed for the whole Electronics Enclosure.
My 3D-Printer is connected to the controller using five 8-pin microphone connectors (https://www.tme.eu/de/details/fc684218/mikrofon-steckverbinder/cliff/) for easy and clean wiring and transportation if ever needed.
I designed the joint on the bottom and top side without tollerances. Therefore you have to sand a little to get it fitting perfectly. I glued mine together using two component epoxy resin for a strong joint.
