I finally upgraded my desk and I want to have appropriately clean cable management. I would need probably 4 of the option shown here, and that's unnecessarily expensive, so I'm hoping yall have some ideas.
Also, ideally they wouldn't be out in the open, since I've got a nibbly cat.
I've seen this done with a section of vinyl gutter before. If you do an image search for pictures there are lots of examples. The version I saw was a reddit link, which I will not utter here.
