I do have a big box 'o cables, though organization is getting difficult. I need some way to organize them into broad categories (USB, audio, power, ethernet, etc).
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.
