HP-41C N Cell Holder

I'm not sure I'd recommend using this, considering that the instructions for using it involve prying the cell holder free with a plastic tool. It would be safer for you to buy a vintage cell holder, or a more faithful reproduction thereof from:

The original springs were much less stiff.

If you're still here, this is an attempt to create a cell holder that can make use of current-production parts. It's not a complete success, because the spring contacts are still too heavy for the user to remove the cartridge by hand alone. I've not noticed any damage on the housing from the pry tool, but time will tell.
