I like Chipp Walters drawer system, but really didn't like the clip on handle.
This remix has a thickened front wall and an integrated handle at the base of the drawer for print-in-place.
The handle can be used to be the drawer open from above and below, and if you pull the drawer out it's much stiffer and can be used to lift even a heavy drawer containing screws.
The author remixed this model.
