I came up with this when I had a bunch of prints to display in the makerspace - and a bunch of filament that needed to be used, made it so you don't have to screw it in from the front, but you can put screws directly into the wall, then just mount. Mounting holes are precisely positioned on the top line for perfect alignment. You won't need too much infill, which means less material waste - and this design could be easily modified or optimized with significant material removal as well.
