Customizable 5V Relay case
thingiverse
There's a multitude of relay cases out there, but since I use mine to power on and off equipment with a 220V extension cord, I wanted to safeguard the 5V relay board and leave some breathing room for the power cord. To customize, measure the board size and the distance between the holes (clearly defined in the support documentation). I have different clones of this board, and the hole spacing isn't exactly the same - it's either 20 or 21 millimeters. The support pegs are centered according to the overall width. **UPDATE**: I've created a new version with even more options: https://www.thingiverse.com/thing:3851101
