MegaTrays
Stack them. See into them. Pull the one you need without unstacking the wall. Color them in whatever filament the bench already speaks.

Workshop
Open fronts, mixed sizes, labels if you want. Print as many as the shelf demands — a wall of bins you can actually see into.

Electronics
Header pins in one tray. Duponts in another. Fine 25 mm steps so a 2×3 doesn't waste a 4×4 of space. Snap to a base plate; reprint a single tray when a new module shows up.

The stack
That's the MegaTray: a bin that grew up. Efficient enough for the bench, finished enough that it doesn't have to hide.
