AA AAA Rechargeable Battery Holder

I decided that it was finally time to organize the batteries in the junk drawer in the kitchen. This thing holds AA and AAA batteries, sorted by type and by whether they are charged or discharged. Obviously, the red section is for discharged batteries, while the green section is for charged ones.

The red color was obtained by putting a pause in after the top layer was printed at the 32mm mark, and changing the filament at that point. You can do this or skip it and get a single color print. Your choice.

I printed it with three shells, and 0% infill until the 28mm mark, where I changed to 10% infill to ensure that the top layers would print well.
