4 channel relay enclosure

I’m building a custom controller for some new landscape lights and I needed an enclosure but I couldn’t find one I liked so I made my own. A little tinkering in Fusion 360, a couple prints, and a few heat-press threaded inserts later, and I have my new box!

I'm using a 4 channel relay board from Amazon with an ESP01 controller running esphome and connected to Home assistant

I also published an example config for esphome and HA. I had a really hard time finding documentation for the board so hopefully this makes it easier.

It uses M4 x 10mm inserts in the exterior corners and M3 x 4mm for the two internal bosses that hold the relay board
