Travel AA and AAA battery holder

thingiverse

When traveling, we often have numerous AA and AAA batteries for various devices. These batteries tend to become disorganized and mixed up in different bags. To solve this issue, I designed a straightforward friction fit case that can accommodate 2, 3, or 4 batteries arranged either linearly or in a 2x2 configuration. The case features a top and bottom section with a simple heuristic: if a battery's dimple faces upward, it is charged. For optimal results, ensure the design works for your AA batteries and adjust the radius as needed based on your 3D printer's tolerances. This model is parametric, allowing you to easily create different holders by editing the SCAD file. Select the desired size and layout, and generate your customized holder.
