I was looking for a place to store my AA batteries where they can not cause a short circuit and they are easy to access. When I was thinking of a place to store them I came up with an idea. I decided to 3d print a honeycomb shaped battery holder that can hold up to 25 AA batteries.

I joined the cylinders together and made cuts on the sides of the print to save filament

If you want to store your AA batteries in this you can download and print from the .stl file here.

I would recommend using low infill for the print because it is very large and you will use a lot of filament.
