i3 Prusa (or whatever) enclosure framing hardware

These are 40x20mm end pieces for 3mm acrylic sheet with 1/2"x1/2"x.055" aluminum angle stock for framing. I made an enclosure for my i3 Prusa printer, they could be used for any other type of enclosure. On my build the door slides up and is held up by Neodymium magnets.
I have made an updated version that uses less screws and is a bit stronger. http://www.thingiverse.com/thing:979414
