Compact AA/AAA battery storage

This is similar to the commercially-available units in that each cell slides out easily, but stays in place until you want to remove it. Cells can be inserted upside-down for used/fresh organization.

I made this because the commercial options didn't have the exact size and configuration I wanted. Other 3D-printed options didn't have two-row configurations in the design I wanted and/or fit too loosely or required a cap.

The pictures show it printed in PETG (for flexibility of the tab. Print it standing up and it doesn't require any supports. Batteries vary in size and printers are not all the same. You might need to scale up or down by a percent in the X/Y directions if things fit too tightly. On my printer (Bambu X1C) all the cells can rotate freely in the holder once they're fully seated past the latch.

Updated: V8 files include a much more robust latch arm which is less likely to break.
