Never be without the right battery again! A complete collection of 3D-printable adapters to convert your AAA and AA batteries to larger sizes (C and D).
General Description
Need a D battery for your flashlight or a C battery for an old toy, but only have AAA or AA batteries at home? This adapter set is the perfect solution.
I designed these adapters with a consistent and robust design, optimized for 3D printing. The set covers every possible combination, allowing you to use AA and AAA batteries in devices that require larger sizes.
The kit includes the following adapters:
AAA ➔ AA
AAA ➔ C
AAA ➔ D
AA ➔ C
AA ➔ D
C ➔ D
Design Features
Unified Design: All models follow the same clean and functional aesthetic.
Easy Assembly: The models are designed to house the battery securely, ensuring perfect electrical contact (we recommend using small screws (M2.5x6) or metal contacts as shown in the photo).
Inspection Windows: Some models feature side openings to facilitate battery removal and reduce weight.
Included Text: Each adapter is engraved with the conversion type (e.g., "AA TO C") for easy identification.
