I made this box to store the amazing math rotators from 3DogPrint.3DogPrint - Multiplication and Division Unzipping Rotator from MakerWorldI don’t need a closed box; I just need something to organize the rotators in the classroom.
The internal size of the box is 85 millimeters. So, it can hold 8 rotators with 5 millimeters of extra space left.

Adjusting the spacing in the slicing software is sufficient to achieve a tighter fit or accommodate more rotators (10 millimeters per rotator).
