These nifty AC power connector/switch/fuse things are available on eBay and I wanted to use them on a new Prusa i3 build. I'm using the box frame so I can just screw this to the plywood.It should be useful in a lot of situations.These connectors are so useful I just keep a half dozen of them on hand.I've got 3/4" screws pictured - shorter would be better, but that's what I have.
