Table/Sill cable mount

This is the first design I've made for 3D printing, but the concept came to me far before I got this Monoprice Select Mini I've used.
It's quite a particular case. I have a home studio with a separate booth to record and needed a way to hold the cables between the booth and the studio itself. As I didn't want to drill the walls, I passed the cables through a interior terrace from window to window. Needed something to hold the cables over the studio tables and the window sills and came up with this.

So the premise was to do something simple that I could attach to a table and a window sill without drilling, and with holes enough to hold the two cables that I have now plus two other holes just in case.

Quite basic, but does the job. It doesn't have top holes because it's designed to be set in place with a drop of hot glue, as I wanted something I could remove easily when moving. With a strong top part to deal with that (a bit rough).

This is the first working model after a bit
