This is a relay box for a two relays board commonly found on Amazon / eBay.
Connect to your OctoPi to turn on and off your printer.
You can see on the photo how I connected it in parallel of the original switch of my Flashforge Creator Pro.
Use M3 screws for mounting the board inside the box, and to close the box.
