Spare Battery Box for Metal Detecting

thingiverse

As a follow-up to my coin probe holster (https://www.thingiverse.com/thing:2846254), I wanted to create a spare battery case that can accommodate different types of batteries used by various detectors. Both my Garrett AT Max and Garrett Carrot use 9-volt batteries, so I designed this box to hold two 9-volt batteries. However, knowing many detectors utilize 4 AA batteries instead, I expanded the space to allow for either storage option or even a combination of both. This versatility makes it easy to store your choice of batteries in the box. You can also repurpose the box as a coin holder by adding some cotton inside. It's your plastic, and you're free to do with it as you please. I've designed the box to be attached to your belt or web gear via two zip ties. After testing this method with my coin probe holster, I found it works exceptionally well. To achieve the best results, I recommend printing the top and case at 100% infill and a .2 layer height without supports. The top features a friction fit design that requires some adjustment to get just right. In my experience, a .2 layer height provides the perfect balance between smoothness and grip. Adjust your print settings accordingly to achieve the desired outcome.
