SainSmart 4 Signal Relay Box / Lid

Built a box for the sainsmart 4 signal relay and huzzah 8266 board controlling it. Will probably be making some changes for ventilation and wifi signal passage. But trying this and if it works, will leave it. Putting it up in case it's useful to others. Done in Fusion 360 for a quick / dirty box. Should be done in OpenSCAD for customization. Some day. :)

Installation: Print it, align the input and output sides in relation to the opening in the box, test fit to make sure everything lines up, test to make sure you can get to the terminal screws, test fit again, hot glue the coners of relay, wire it up, done.

As for the esp8266, my plan was to hot glue it to outside of the box on the side. But in hindsight, I might make provisions for it to be mounted inside the box and make an opening for a 5 volt power cable. Will post the update when it's ready.
