4 channel relay module box
thingiverse
My 4 channel relay box. I made this box to enclose my 4 ch relay module that is running some of my Christmas lights. I have a box, a lid, and a shelf. The box has a hole on the left side for wires. I have 4 small square holes for the relay LED's. There are 4 holes on the back side for the relay wires. The holes are only big enough to access the common and normally open contacts. There is also room for an Arduino Nano inside. R1 Revision I bought another 4 ch relay board and noticed that my LED holes didn't line up quite right with the LED's. I shifted them over slightly so they line up now. I also changed the relay access holes. I/We can reach common, nc, and no now, all of them. I didn't think my printer would do good with a 30mm bridge, so I made 12 little holes for the relay contacts. They line up.
