Turn a scrap box and paper cups into a low-budget tray. Basically, glue the cups onto a shallow box and then use a nested set of cups for storage.
The quickest & cheapest storage tray I could make. It holds little hardware & electronics stuff. Great to sort with …. sort buttons .. sort electronics … sort springs … sort gears …. screws, nuts, bolts … you name it.
If it fits in the cup it can be sorted, stored, and then ignored!
