This is a box with three compartments to store those batteries without a home. I reduced the material used on the box with a familiar pattern on the bottom. The ‘C’ compartment holds 10 cells and the others will likely hold more but I didn't have enough to test.
I printed with 4 walls, 5 top and bottom layers and 40% infill, but there is not much infill and less would probably work just fine.
I printed in ABS but other filaments would work as well.
Footnote: this is my first published design, I welcome any feedback!
