These are 27 gallon totes at HD. They are sturdy and cheap. But are only good for throwing tons of junk and stuff and whatnot into them with no chance for organization of easy access to anything but what's on top.
Would a grid/shelf/tray system that you install in the tote sell to the average homeowner? There could a vertical "pull up and lock" system for totes on the floor and horizontal shelf system you pull out for totes horizontally on a shelf.
Easy to mock-up with 3D printing. Modular so you can make things fit efficiently.
