3D printed AA battery holder

I have a lot of photography and videography gear that uses AA batteries. I prefer AAs over the built in Lithium batteries a lot of gear comes with now, because you can get them anywhere and they can be shared across devices. I’ve owned a lot of different AA battery holders/containers over the years, but I’ve never really been happy with any of them.

I’ve faced a few issue with holders I’ve owned, but only two are of any real consequence. The first issue, is that they are almost always a flat or rectangular container that requires a dedicated spot in my camera bag. The second and more annoying issue, is that ever single container only allowed the batteries to be stored in one orientation, usually with the positive contact facing up.

Custom holders of my own design have been on my project list for years, but until I got my 3d printer I had no realistic way of making them. With my printer up and running and a decent PETG profile in hand I sat down last week and designed my idea of a good holder. The Photos below show what I came up with. Each holder can hold 8 batteries, with either the positive or negative contact facing up. Being able to store the battery in either orientation is a simple way of indicating a battery needs charged. In the heat of the moment, this means you don’t need to think about what batteries are good to go.
