3D-Printer Controller Box

This is a "simple" control-box containing all you need for running two 3D-Printers using two instances of [Octoprint](https://octoprint.org/download/) (OctoPi) on a Raspberry Pi 3+ (on different ports).

Update 2019-11-01: Added "Big Box 2 v1.stl" - For the "other" relay board (better option).

This gives the following:
* Power-control / printer (ex. PSU and lighting).
* LED-status (up to two ledstrips).
* A Power button for the Raspberry Pi (real shutdown).
* Two physical buttons to use for whatever you want (I use them to turn the power on and off to the printers).
* Two AM2302 for monitoring temp and humidity (in an enclosure for example).

What I used:
* Raspberry Pi 3+
* [USB-Relay board](https://www.ebay.co.uk/itm/5V-USB-Relay-2-Channel-Programmable-Computer-Control-For-Smart-Home-UK-seller-/292838059668?hash=item442e822e94) (but I recommend an easier way with [this](https://www.ebay.co.uk/itm/5V-12V-or-24V-1-2-4-8-16-Channel-Relay-Module-Arduino-PI-ARM-AVR-DSP-PIC/
