Based off of tjmck's "Network Cable Organizer".
For my home network cabling I needed a comb that supported larger bundles than tjmck's existing design. I went ridiculously larger than my needs were, but this comb can effectively make bundles of 96 cables.

Designed for network cables from 5mm to 7mm diameter.
Most Cat-7 and quad-shielded RG-6 will still fit through the holes (7.5mm), but will not easily load from the sides.
