Nikon EN-EL23 Battery Case

This is a very simple case to hold two Nikon EN-EL23 camera batteries. I didn't make a lid as I want the batteries quickly accessible in my backpack. This one protects the electrical terminals and offers some crush protection as well. The batteries fit snugly. They won't inadvertently fall out. Three ridges in each compartment, visible in the photos, take up any clearance and grip the batteries firmly. The batteries are inline rather than back to back so that the case lays flat and makes best us
