Hello, This make is great; Tgank-you :-)

Thanks for your comment!

Thanks a lot for sharing this. I printed this and the AA battery is too loose in it. Is that by design?

I do not have this problem. My AAs have a very tight fit.

Thanks! My son reaaallllly wanted to play with his toy that needed 2 C's when all we had were AA's. This was perfect!

Thanks for your comment!
That's why I love 3D printing. ;)

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.

I think this is the best one yet on Thingiverse. It expands and fits every different battery I tried in it. Not to loose and not too tight It's just perfect!
