I had had enough of AA batteries rumbling in the drawer. So I have designed an Ultimate Honeycomb Battery organizer.
This geometry provides high strength, high pack density and so versatile options of stacking the honeycombs - see attached photos.
Organizers can be aligned both horizontally, vertically and on on the side. A set of two can create a safe box for batteries. Plus terminal is used to aligned tiers of holders, plus thickness of the bottom protects it against contact.
