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.
I used rectilinear 15% , but mainly to have a flat regular bottom.
the one i printed (see the photo) was sliced by repetier host / slic3r with a size factor of
This was enough for my screws, and easier to fit on a 20x20cm printing bed. as it becomes a 16x16cm box.
Anyway, size it the way you want (or can).
I used Sketchup, and provided the skp file if you want to modify the model.
