Disclaimer: Due to the recent incidents (things appearing on ebay) I just want to make something very clear: I do not allow any commercial use of my STL-files, my designs and my photos!Description: It is Christmas and all shops are closed. But I really do need some c-type batteries and I need them now. 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.Print it - insert an AA battery - smile!
