This is an aid for cable management in large wiring plants, for bundles of 24 cables of Cat6A or equivalent. It was designed manually by gust334 (Reddit u/gust334) per a Reddit post from u/GonzalesV7 titled "Cable Weaver Needed" at https://www.reddit.com/r/resinprinting/comments/1pmomhe/cable_weaver_needed

Feature size is sufficiently small that this will need to be printed on a resin printer to make the legends visible.

The aid is designed solid and should be printed solid for maximum strength and durability.
