ESP32 Box with cover

This will fit a ESP32 dev board, a small relay and small 120v to 5v power supply. I used this design to fit my ESP32 to my Ender 3 Pro for ESP3D control of my printer. The small opening on the one side will fit the RX and TX wires as well as a ground for the control board. The bigger opening will fit a wire lock for the 120v wiring.

I will not inform you how I have it wired up but if you decide to try this, this box may work for you. It also mounts on the bottom rail near the Z stepper motor. You may need to drill out the mounting holes depending on what size fasteners you use.
