This my version of simple desk drawers.

The parameterized file contains the casing and one drawer as individual render options (print this as many times you need) fitting the slots in the casing. The casing is partly open on the back to save filament and to allow the drawer contents to “breathe”.

You simply configure how much space your individual drawers should have on the inside, everything else is calculated automatically. The unit values should be seen as in millimeters.
