Step by step boxed screw manager

I quickly designed this box, not printed yet, but sure will be useful for sorting the screws while disassembling a complex device with many sort of screws and many steps.

Just put the first screws in the box #1, then at the second step put the next screws in the 2nd one, and so on.

step back from box 16 to 1 when reassembling your device.
