After lots of versions, I think I have made a nice cable dresser. Designed for Cat 5, may need to be slightly scaled up for Cat 6 and beyond.
Directions (if you really need them)
Print two at a high infill for strength.
Put them together and put your ethernet cables in the groves.
Secure with a velcro strap around the body.
Slide and secure.
