Here is an updated 3d printed battery storage bin. This design holds 45 xAA, 46x AAA, 10x C and 7x 9v batteries. My next version will be modular, so you can print the battery types you want. Th previous version only worked with certain brands of batteries, i have made the holes bigger so they fit generic battery brands as well. I have also included the fusion files if someone wants to tweak it.

For printing I used PLA, with 10% infill, no brims or supports required.
