Small Parts Storage Box Generator

Screws, nuts, washers, beads and resistors are much easier to find when every type has its own cell. Choose a grid and print a box sized for your workbench drawer or shelf.

    A bigger corner radius matters here: with a radius of 5 mm or more you can slide tiny parts out of a cell with a fingertip instead of chasing them into a sharp corner.

    Thin walls for many cells

    With lots of compartments, the walls take up a surprising amount of space. A 1.2 mm wall (three lines with a 0.4 mm nozzle) is plenty for small parts and gives you more usable room than 1.6 mm. Keep the floor at 1 mm or more so the box doesn't flex when you pick it up.
