Just my personal take on a AA battery holder.
Print how you'd like, uses 3mmx6mm pan head screws for terminals, and i used som solar panel ribbon bus wire for the bridge connections. I will probably take it apart and put the pan head screws in backwards to give a better connection surface and then jam nut a washer on the bare thread end to make a sort of adjustable thumb screw.
