Many tool companies offer “jobsite organizer” boxes for small parts. Our local home stores carry DeWalt, Stanley, and Milwaukee products that are all on the same pattern: plastic briefcase-style box with a handle, a clear lid, and removable bins inside. Some of them can also be stacked and linked together for more storage. But since I'm not a contractor (the usual customers for these), I tend to acquire smaller quantities, but in a greater variety, of most classes of part: screws, plumbing fittings, crimp terminals, etc. So I usually want more resolution, i.e. more and smaller bins or dividers, than the organizer offers. For that, I have a 3D printer.

I selected the Milwaukee 48-22-8030, despite it being red, because it was the only one that had metal latch hardware, because the handle placement gives it the best ratio of internal to external volume, and because the Milwaukee organizers can be opened while linked to each other (the linking latches are only on the lids). In Onshape I designed a bin that would subdivide the smaller square bins diagonally.
