Everyone knows battery storage, but lets make it faster and cheaper to print. While still functioning the exact same.

Pre-made 16, 24, and 48 battery capacity holders. My own optimized version of a simple battery storage container for your drawer or workshop. 

Printing:
Any settings you like, most settings don't matter since the walls are only 1mm thick so theirs no room for infill.

Filament:

Any filament works.
