Needed a quick thing to hold a board I had laying around to support my screen on my new desk.
Quick draw and print.
sliced with Slic3r because of the honeycomb infill, printed in transparent PLA on glass.

I printed 2 because on the one side the board where the screen stands sits on a box.
I glued the holder in place, but I guess this wouldn't be needed if you're not planning to move anything around a lot.
