Snap Circuit 4-Channel Relay Module Enclosure
thingiverse
I got tired of my four channel relay getting kicked around. My workbench also has an aluminum plate mounted to it so you can imagine how hard it is to do electronics on top of that. So... I created an enclosure for it. My kids have the Snap Circuit Toys and so I designed this to use the Snap Circuit base board as my protoboard. It was modeled off of the Snap-Ino Arduino Module. You may need to adjust this design to accommodate the layout of your relay but all the cutouts are there. Once it is printed, the relay can be dropped in. The posts can be deformed to make the mount permanent or leave it as is. It will wiggle a tiny bit but it can be removed easier in the event of failure.
