Under Desk Drawer with Keeper, Middle Section, & No holes.

Quick remix of Paul's cool Under Desk Drawers with a hidden keeper so it doesn't pull out too far  and a no-holes drawer option.  All parts fit in a MK4/3 single print.  Twisting keeper allows for less fumbles during assembly while still preventing the drawer from pulling out too far, but also allows easy removal for dumping out/cleaning.

Updated: 
-Added middle section option so you can add more drawers. KYZ Design suggestion I think.
-Slightly enlarged holes to allow for wider variety of screws. (#4, #6, ie. cheap at Home Depot)

Printing:
Turn on supports for the underside of the handle.  I printed mine at 0.3 layer height with 3 perimeters and 20% infill.

Instructions:
Screw in sides so the notches are at the facing the back.  These prevent it from being pushed in too far.

Decide where you want the drawer to stop pulling outwards and screw in the keeper centered at that point.   This should be close to the lip so you can reach it with the drawer inserted.

Twist the keeper 90 degrees so you can slide in the drawer past it.

Now reach inside and twist the keeper 90 degrees to prevent the drawer from pulling out.

Lovely Fusion360 render 'like it's 1989!  …It's pretty Sweet! :P
