Project box
thingiverse
Key piece for generic project box, make the base from lexan, or other plastic, screw one of these to each end, bend a piece of metal into a [ and fit over top, screw holes in the sides. (just barely viable in one of the pics, sorry) The front and back are separate so they can be easily customized.
