Designed this simple and universal under desk mount after noticing a lack of premade alternatives.

The "male" part must be glued to the thing you're mounting and the "female" part can be screwed to the underside of a desk. The hole in the middle can house a wood screw without it interfering with the sliding mechanism.

Printing them like I arranged them in the STL allows for the least support usage (AFAIK). I also attached the SCAD file in case you want to make them with different dimensions/add a screw hole to the male part as well or whatever you may want to do.
