Raspberry Pi 4 case with built-in power supply

Warning: If you're not familiar with mains wiring, abandon this project and opt for the official Pi USB-C power supply instead. Raspberry Pi 4 demands a 5V 15W USB-C power supply - or if you'd rather avoid using a plug pack, create this design, purchase an IEC C8 power socket, a Mean Well MFM-15-5 module, and make two solder joints to construct a case with a built-in power source. The Pi rests in one half of the case, exposed for access to headers and other connectors. The power supply module is situated in the opposite half of the case. When operational, keep the lid on the mains section closed, while 5V DC - identical to what's delivered by a plug pack - exits to power your Pi. I crafted this design to enable attaching a Pi to my 3D printer's casing without needing a separate power adapter. This particular design lacks mounting lugs (as evidenced in the orange case image), but you can easily add them wherever it suits your needs.
