AA to C Battery Adapter
by blecheimer, published
Simple solution - print an adapter for rechargable AA batteries (I have a lot of them).
There are some adapters from AA to C on thingiverse, I tried them but they did not do the job. Some are too thight for my rechargable AAs, some are too big and so on. So I just made my own adapter.

good design, I like the springy "spokes" good idea. I used to make something similar, Just a plastic battery with a brass rod (wire) down the center as a conductor. Useful for reducing voltage (say 4 to 3 or 2 batteries) on certain devices I was testing, while using a standard Radioshack 4 battery case.
