Under Desk Drawer for square steel desks.
Most printed drawers I was able to find on here rest flush against the mounting surface of the desk, this design offsets the top of the drawer from the mounting surface by 25mm - a common width for desks constructed from square steel. I included a recess in both the drawer and the sled to add magnets, though this doesn't seem to do much for the detent.
Recommended that you print using supports for both the sled and the drawer. I was able to get them to work with minimal cleanup using tree supports.
