Plastix box shelf

After buying twenty boxes (6.5 x9 .5 x 2.5 cm) from Aliexpress, I decided that it was necessary to build a frame to keep them organised.
The solution I found involves printing a rear frame, a front frame and 24 L-shaped profiles to be glued.
Everything can be done without any waste of material for supports, and by making the L-profiles with the correct filament orientation, to prevent them from becoming brittle.
I do not plan to release cat.stl
