Relay Box with 2020 mount
Description
I've designed this relay box to house a single channel relay and mount on the 2020 rail under the power supply on a Creality Ender 3 Pro. I'm using the relay to control turning the printer on and off through OctoPrint. The lid is zip tied (2.5mm wide) on to make sure it's properly secure as there's exposed contacts inside with 240v running through them. Once setup it should only need opening if the relay develops a fault so doesn't need to be easy to open. Support is needed (touching build plate only) and infill can be left at 20%.
