There are some 3d printer models for building grids of individual cable organizers (https://makerworld.com/en/models/946444-gridfinity-cable-org...) but I have too many cables and my collection is too dynamic to well-utilize something as static as that.
I very much recommend them. As a bonus, you can label them if desired. (Print a label out, or slap some tape on there and write on that, or just stick a sheet of paper inside the bag and write on that)
