RPI electrical Controllerbox for 3D Printers

This Controllerbox is part of my Ender3 Enclosure project: https://www.thingiverse.com/thing:3697275

It can also used for all projects need an Raspberry PI case with room for Power Supplies and electrical components.

### Printing
My designs aimed to be easy printable, so no supports are needed if you rotate the model right.

### RaspberryPI / Controllerbox
The printed controllerbox in this project provides a mount for RaspberryPI, 2x LM2596S DC-DC Power Supply, 1x FRC Relay, 1x Custom PCB, 1x 40mm Fan.

I cannot give a clear advice how to build this because its adjusted to my use case and some parts only used because i already owned them (The IRLB4030 nfets for example are a hugh overkill but have them in spare from my eBike projects).

See the attached photos and electrical diagrams to get an idea how to build your own Controllerbox.

Parts (as a quick start):
* Raspberry PI
* RPI Camera Module
* 2x LM2596S DC-DC Power Supply
* 1x 40mm Fan
* The printed enclosure
