This is what I was trying to print the other night when I got the mass of twine instead. This, friends & neighbors, is the corner piece of my 3d printed computer case. The top is going to rest on those little pegs and after I clean up the pieces, they will all snap together like a puzzle. I was hoping to make it large enough for a Micro ATX motherboard, but that's not going to happen with this build. Instead, it's going to be Mini ITX. It will still have more than enough horsepower to run a Makerbot.
