I have a set of these, with the smallest on my desk to hide/control some of the clutter.
The larger ones will fit power strips too.
There’s a lot less clutter to hide now that I have a custom snake to connect my modular with my audio interface, but there are still a couple of optical cables, some USB cables crossing my desk, etc. And it makes a handy stand for my Nixie tube clock and some rubber duckies.
