Small Parts Storage Box
thingiverse
A handy little compartmented box for storing screws, washers or anything you like. It latches closed and shouldn't come open accidentally, even if you drop it. (Requires 6 M3x20mm screws for assembly.) There are dividers top and bottom, to ensure things can't pass between compartments when the box is closed. This is a customized version of my "Customizable Rugged Waterproof Box": https://www.thingiverse.com/thing:3338826 This version uses the v-grove rather than an o-ring, so it is not fully waterproof but it should be well sealed against dust. See the cross-section images for the correct hinge and latch assembly. Here is a video of the latch operation: https://youtu.be/6OlaYMMWIgA (edit 2019/02/27: updated "hinge.stl" to correct model, it was previously a duplicate of "hinge_single_axis.stl")
