I found some cable combs on the internet but none of them fitted my needs (we got thick CAT 7 cables at work). The cables didn't go inside the available cable combs out there.

So I decided to start from scratch and build my own ones in Sketchup Make 2017.

Thinner cables will fit in there as well. I've tested CAT 5 as well.

Feel free to create your own ones with my *.skp files :)
