This is a drawer I designed for my desk. It features a spring-loaded stopper that prevents the drawer from falling out when fully opened, while still allowing you to press it down to remove the drawer if needed.

The sliding rail can be screwed to the underside of the desk (7 × M3 screws). However, since my desktop is quite thin, I used strong double-sided tape instead: https://s.click.aliexpress.com/e/_c3nF2gLL

The front holes are spaced 64 mm center-to-center, allowing you to use one of these inexpensive handles: https://s.click.aliexpress.com/e/_c2JpBfrn You will need two short M4 screws.

The main drawer file includes two bodies: the drawer itself and a top stopper. The stopper is optional and can be removed in the slicer, as the sliding rail already has a rear stopper. I included it because my desk has a 20mm square tube at the front, which I use as a stop to prevent the drawer from sliding all the way back (see the photo of the underside of my desk).

While the drawer slides quite freely you can use a little grease to make it smoother, i used this one https://s.click.aliexpress.com/e/_c3W8vBcZ
