Battery Adapter: AA to C

cults3d

The adapter lets you use an AA (LR6) battery instead of a C (LR14) battery. It stands at 12mm tall: you can stack four of them to get the exact battery height, but if you want to save plastic, you can also use two or just one in a hurry. Compared to items 39478 and 4205: * Less likely to scratch the battery labels (eneloops are prone to scratching with the old design). * Height adjusted so four of them stack up to an exact battery height. * A sturdier design, but more flexible inside to accommodate big variations in AA battery diameter: the inner triangle acts like a spring. * Simpler geometry: a bit faster to print, 20% taller but still uses the same amount of plastic. * More resilient to shock and breakage.
