2x1x2 FreeGrid boxes, plain and with subdivisions into two and three compartments. Each with a variation that has room for a label and a curved ramp on the front to make it easier to scoop out the contents. Can be printed without supports.

The most important thing is to make sure your magnets have the same orientation throughout the whole system.

More about the FreeGrid system and FreeCAD tools to build your own modules is available on our FreeGrid page.
