This replaces the need for an expensive basket to hold the cables under your desk. Simple print one or more out of these and combine them as needed to hold your cables to underneath your desk. 

I use it to hold extension cords and other cables needed for my desk and get them out the way of my feet. 

Best is to put them on your desk and them push the desk up against a wall. Or if you add some tape to make them stay in place on your desk. 

Just print @0.2mm layer height and about 15-20% infill in PLA and that should be fine. No supports needed.
