Mixed Batteries Holder

thingiverse

This is a great tool to help you organize all of the batteries you have. It is a modular system, you can adjust the amount of batteries. I decided to keep all AA and AAA batteries in one container. The box and the battery rack are designed to be printed separately so that you could remove the rack and use it as a small toolbox. PS. I've found that some AA batteries are a little thicker than others
