Ender 3 Control Box

**Status:** The STLs are now working well, but it is missing a bit of information on how to assemble. However they should be safe to print.

This is a 3D printable control box to replace the mainboard enclosure. This enclosure contains:

- A [Raspberry Pi 3B](https://www.raspberrypi.org/products/raspberry-pi-3-model-b/) for running OctoPrint,
- A [BigTreeTech SKR 1.3 main board](https://github.com/bigtreetech/BIGTREETECH-SKR-V1.3),
- (optional) [A Google AIY Audio Hat](https://aiyprojects.withgoogle.com/voice-v1/) with Speaker and microphone,
- 2 LM2596 Step down converter for providing 12V for the lights and 5V for the raspberry Pi,
- 3 5V relay switch modules controlling the printer, the lights and a fan for the raspberry Pi.

This installation is controlled using an OctoPrint plugin available at https://github.com/damienmg/OctoPrint-ControlBox.
