Raspberry Pi Chassis Mount for Prusa MK3s Printer

This box can be mounted at the top of the frame, above the Einsy box.
The box can take either a Pi3 or Pi4 thanks to it's removable bezel.
The box is designed to use a 24V to 5V power converter, and be connected to the printer's main power supply input.
Connection to the Einsy board can be either via the GPIO port, or via the USB connector.
The Einsy spacer can be used to provide access to thread cables down from the top to the bottom of the printer.
