Batteries are the bane of almost every optics existence, and that’s why most of us probably carry around a zip-loc bag full of random batteries of varying charge states – some of them are likely empty as well. Although I haven’t quite committed to purchasing my own 3D printer just yet, I did have an idea that I wanted to pass on to my good friend “Hammy” from Hammy3DPrints. Excited about my idea (having a small compact box that has all the basic batteries in it), I called him right away, only to find out that he previously had a version of this battery box – it just needed a few touch-ups. A few days later, I had a fresh print show up, and today I’m going to tell you why the Range Bag Battery Case from Hammy3DPrints is the best damn thing he’s ever made.
