It is a maxim that the more you engineer your storage solution the less it holds. There are exceptions but some examples are;
Before and after pictures of a closet system, before: 40 pairs of shoes jumbled in a box, after: 12 pairs of shoes neatly in the rack.
Coin collection in neat folders use 1 cubic foot, or tossed into a quart jar only half full
50 router bits in a wooden block, 4" x 3" x 12" or tossed in a soup can.
Obviously organization is needed for these but it takes up space.
