Battery Holder with optional Gridfinity base

Simple holder with compartments for AA and AAA batteries. It requires a minimum amount of plastic to print.
I don't like the idea of having different organizers for these two types of battery so I created this design to keep them all in one place. You can also print dividers to separate discharged batteries and keep them in the same place.

### Versions
