Modular organizer boxes 51x31x106mm (single) and 167x31x106mm (triple)

There are two types of the single modules, one with a 0.25mm notch and one without.

The idea is that the one with notches will make it easier to get a snug fit while it is easier to slide them together. The one without the notches can be difficult to slide together.

Three different single boxes, with one, two and three spaces

The triple box has two designs, one that is open and one with loose walls that makes 9 spaces

Notes:
I suggest you test print the modules to see if they fit each other. Print two modules e.g. 30mm and look so they aren't too tight or too loose.

It makes a big difference what perimeter width settings you have, i.e. 0.42mm might be perfect and then 0.45mm will be too tight.

Recommended layer height is 0.20mm
