Raspberry Pi / Arduino Nano / Relay Module Case

## Description

This *thing* was designed to fit a Raspberry Pi 3 B, a 4 channel solid state relay board, an Arduino Nano (with removed headers) and be mounted under a desk; it could also be mounted on a wall.

the Raspberry Pi runs Pi-Hole and Node Red
the Arduino Nano is flashed with Firmata Standard and wired to the RPi via serial, with the use of a logic level converter; it's powered by a 12V PSU via the VIN pin
the relay board is wired to the Arduino Nano
a DS18B20 temp sensor is wir
