Storage for Rechargeable Batteries

thingiverse

I have a lot of batteries, especially rechargeable batteries with various powers. I needed a storage in which I could have: - batteries recharged long ago come out first, - batteries of a similar form factor but different capacities sorted in different places. So I came up with this case, adaptable for AA, AAA and 18650 batteries, actually any cylinder-formed batteries. It comes in 2 parts: the case itself, and an extra piece that prevents other batteries from coming out when taking the bottom battery. You simply organize them from right to left as weaker to stronger (or the opposite if you prefer that!), and you add new batteries on top of others. Then you easily pick them from the bottom with one or two fingers, the others will simply fall in place. This is also fully customizable in the scad file: choose your battery size, the number of columns and number of batteries per column.
