On a Baltic birch shop box for holding accessories, use Dominos at each end (3/4") to line up the box top and bottom, then (in theory) use spring latches to latch to box shut. I'll post a pic if I remember after the latches get here.
I tried to put said accessories in a systainer, but that failed due to a mix of accessories that were slightly too large and slightly too awkward to be lined up efficiently. My box is smaller in volume, fits in my existing shop drawers better, and allows better access than the systainer would have.
I need three of these boxes, and built only one so far. After I built it, I found a Really Useful Box that was just the right size each of the last two boxes, allowed for reasonable organization, though not as good as my custom box, and fit very nicely in my shop drawers. However, the Really Useful Boxes were $12. and my custom box has at least $12 of Baltic birch, and I have time and hardware in the custom box. The custom box does look better though.
