tiered storage box button cell AAA AA C 9v battery holder

I've been using Perinski's tiered storage box to hold all my bits and bobs, and I wanted a place to also store all my batteries. I found that the 30mm x 8 compartments fitted most battery sizes very nicely, such as AAA and AA, C, and 9v, but I also needed a way to store button cell batteries. I designed some inserts that fit into the storage box for small, medium, and big button cell batteries of 3 different thicknesses, to keep all batteries separated and have pretty much no risk of them shorting out with any other batteries, and also keep them in a container if they decide to leak.

id highly recommend seeing the original tiered box design by Perinski as this box system is highly customisable, and you can add other boxes to this one if needed.
