Well, maybe I'm crazy. I like building in plain Hammond boxes. And I like using removable power cords. I was sitting around a couple weeks ago thinking about IEC chassis holes. I can either tediously cut it with a Dremel, or buy an expensive punch. I don't like buying expensive punch. Round holes with a step bit take 10 seconds, but the (minor) problem with mounting the socket in a round hole is the look. So I sketched a little adapter the IEC socket could slide into, and then bolt the whole thing into the chassis. I talked to my brother-in-law who's got a little 3D printer. He did some magic, made a computer file, and printed the thing. He said the cost to him was probably about 50 cents a piece. I don't sell amps. Maybe this doesn't look professional enough for people who do. But for my own use I like it a lot more than a socket in a round hole.
I wanted to share the idea and ask if anyone else has any use for this? I can ask him for the file and post it here, he said anyone with a 3D printer should be able to print it. I think you can even take the file to some stores now and have them print for you (like Kinko's and Staples). Also, if this is a stupid thing to use for some reason, let me know!
I did't have any scrap metal and haven't started my next build yet, but here's an example of it on a scrap piece of 1/4" plywood. The adapter is about 2.5mm thick and I mounted it over a 1 1/8" hole.
Worth noting guys can 3D print metal objects now, too. I don't understand it. But they do it.
