I have created a simple desk bin that can be attached to any desk that is not thicker than 20mm though thinner desks will require the use of washers/shims to make the clamp snug.

The bin is a two part system the bin been the box item and the clamp that attaches to the desk. I made mine using PLA though I would suggest for the clamp using harder materials such as ABS/PETG if the bin is having heavy items placed on it. The bin is designed to slide off the clamp for easier emptying.
