Nikon EN-EL14 spare Battery tray for classroom

thingiverse

I have a classroom set of Nikon D5X00 series DSLR camera batteries and needed a way to organize them into charged and depleted groups. Charged EN-EL14 batteries can be placed upright, while depleted ones should lie on their side. The batteries tend to fall like dominoes if not secured properly, so this system aims to prevent them from hitting the floor.
