Raspberry Pi 4 case with built-in power supply

pinshape

Warning - if you are not competent with mains wiring, leave this design alone and buy the official Pi USB-C power supply. Raspberry Pi 4 requires a 5V 15W USB-C power supply - or if you don't want to use a plug pack, print this, buy an IEC C8 power socket, a Mean Well MFM-15-5 module and a couple of solder joints later you have a case with a built-in power supply. The Pi sits in one half of the case exposed in the usual way so you can get at the headers and other connectors. jThe power supply module sits in the other half of the case. In use you can keep the lid on the mains part and only 5V DC, same as the plug pack, comes out to power your Pi. I made this to attach a Pi to my 3D printer's case so that it could be powered without a plug pack. The design here does not have mounting lugs (as the pictured case in orange shows) but you can easily add those where it suits your situation.
