SONOFF case for relay switch module
thingiverse
This case is designed for a eWelink compatible relay card, making everything accessible after mounting the case so you don't have to open it every time you want to make a change. I used M3 screws mounted upside down as buttons and a piece of transparent plastic cut to size for the LEDs to be visible on the outside of the case. To assemble, I glued the top and bottom together using a hot glue gun. You can purchase the relay here: https://www.amazon.co.uk/OWSOO-Control-Wireless-Universal-Support/dp/B07DS44LXJ
