A different holder for each type of battery. They are all the same length and clip together in any combination you want.
Thank you Shrunkyboy, I have uploaded your AA Battery holder to add to the collection. Nice work on the coin holder too.
My computer caught the flu a while back and I lost all of my design files. This was one of the ones that was low on the priority list to redsign so I didn't get to it for a while. I am hoping to add more modules for different things you tend to keep on a desk. Ideas anyone?
