Octoprint on Raspberry Pi for Felixprinters

Introduction

We have 9 felixprinters at our school (9 x TEC 4.1). Often we forget to cut them from the power over weekend. We wanted a solution with a better manual interface, a camera to watch the print remotely and the possibility to switch them off remotely. Fortunately there is octoprint and octopi.

Hardware

We use Raspberry Pi 3B+'s with the raspi camera and the official Raspberry Pi touch display. A 5 V cooling fan 50 mmx50 mmx10 mm (e.g from MANOUII (amazon)) and a relay breakout board (e.g. relay shield from wemos.cc).

To reduce the design work I combined some designs from thingiverse.
