Under desk shelf

I printed this with Bambulabs yellow PETG-HF, a .6mm nozzle, .2mm height, .62mm width, 5 top and bottom layers,
10% 3D honeycomb infill, and 6 walls, tho I'm sure you could get away with fewer.

Added some untested alternate models to include a shorter version and a version with a slot on the back wall in each size.

Added screenshots from Orca with dimensions in their print orientation.
