This case is for a eWelink compatible relay card. Everything is accessible when the case is mounted so you don't have to open the case everytime you want to make a change.

I used a pair of M3 screws mounted upside down as buttons an a piece of transparent plastic that i cut to size for the LEDs to be visible on the outside of the case.

I glued the top and bottom together using a hot glue gun.

You can buy the relay here:
