Raspberry Pi Relay Case

thingiverse

This is a case to hold a 4 channel relay board. You can either print the 'tight' lid which is held on by friction, or the 'magnet' lid. For the magnets: You'll need 2 8mmX3mm hobby magnets. Glue one in the base and one in the lid. Of course, make sure when you glue the magnets, you put the north/south sides facing each other so they attract. These hobby magnets are super cheap and it's so much easier to pull lids off. I've used them in all the cases I've printed. They hold tight, are easy to take off, and line up perfect when you want them back on. I've also included both the magnet lid and the tight lid without 'slits'. I like the wires coming out the top, so that is what works for what I need. But if that doesn't for you, print the no slit version and add your own holes for wires. The board is held tight by the 'snap' fittings, and they work ok. But for such small tolerances, I recommend heating up the left and right stands with a hair dryer, put your board in, then press them in and around the board to hold it tight. The picture of the magnet in my base is messed up. The print id fine, it's just my nozzle screwed it up and I didn't want to print a whole new one. There are 2 holes in the base to screw it on to whatever you want.
