My standing desk came with something I’d never used before — zip-tie adhesive backed mounts. They’re great. Each one has a plastic square with an adhesive back that sticks to the underside of the desk, and the other side of the square has a zip tie that cinches tight around a cable or cables. It made it so much easier than previous methods to get cables out of sight. This isn’t the exact model that came with the desk, but it’s similar to this:
Also, after years of trying to get unused cables organized, I tried a couple of these bins and ordered several more, and now have the bins stacked neatly and labeled in a storage room, with a pullout drawer on each one:
They’re just the right size to hold several of each type of cable I use, from monitor cables, to USB, etc.
