Espurna Board is an open source remote control relay based on ESP8266 for IoT projects. I had modified PCB layout a little bit to fit my AC-DC 5V converter module.

Having this board on table is very handy at creating and testing IoT projects. However, as it's playing with mains (240VAC at EU), exposed traces and terminals on a PCB could be very dangerous, thus a housing would be nice to have, at least as a protection layer to some extend.

Housing is designed with Fusion 360, file attached, feel free to modify. Two housing parts sandwiched espurna-board in between, secured with 4 pcs M2*6mm Phillip-head screws.

Happy design and printing :)
