There are plenty of table organizers to attach to the edge of a desk or even underneath. Neither of these types take care of cables you're trying to run down a desk leg. My desk has square metal tubing for legs. I wanted something that was easy to print, did not require extra hardware, and would be easily scalable for any square table leg.

There are a few clip-on cable organizers, but these don't have the tension that this model creates.  Additionally, they are designed for a few small cables at most.  This model can accomodate many cables of many sizes, from USB-C to 120V power cables..

The first-half of this cable organizer has a wide mouth cable bracket suitable for cables you plan to run or cables that are already in place behind your desk. The second-half of this cable organizer slides over the nibs of the first half. A slight angled edge on the second-half means that as you slide the second-half over the first-half, you create greater tension with which to hold on to the square table leg. The result is a easy to print, hardware free solution that will stay in place and neatly stow cables as they run down one of your desk legs.

I've included a parametric Fusion 360 file for customizing for the size of your desk's square legs, or for just remixing this model.
