Holds 12x AA batteries. Prints upside down (load batteries from top) without supports.
Note: this will NOT fit Duracell AA batteries. If you want to use Duracell (or similar), you'll have to scale the X and Y down to 97%, but not the Z. This is because the batteries I used for mine (Amazon Basics and Eneloop) are slightly larger than typical.
The author remixed this model.
Now with a maximum capacity of 12 AA batteries! Also now fits Amazon Basics batteries, but doesn't fit Duracells (see description for instructions).
