Screw Safe, screw tray

I made this tray to avoid mixing up screws or other small parts when repairing toys or other devices. At each stage of dissassembly, batches of identical screws/parts are removed and placed in one of the labelled compartments. When repairing complicated devices, I find it useful to take photos of the device being repaired corresponding to the associated compartments to aid re-assembly.
The tray can be scaled up or down as required.
