Ethernet Cable Combs based on muzz64's cablemanager_ethernet.stl. Created a variety of sizes (sorry, not parametric) and notched the sides to prevent slippage of a zip tie or velcro. If you want something bigger than 16 cables, you probably need to go with a round comb rather than this linear style.

All STLs were run through Netfabb Cloud to ensure validity and printability. Additionally, the notches in the sides were designed to avoid 90 degree overhangs, so you should be able to print these without any support.
