AA Battery Strong Safety Case

thingiverse

**Ver 1 Strong wall design great for keeping batteries from shorting out or crushed, will also protect them from normal drops and hits. **Ver 2 Everything that Ver 1 does but it allows for TPU printed inserts that further absorb shocks and vibrations. It greatly increases protection for the batteries. **Ver 2.1 Lid now has tabs on the side instead of a solid wall to help shorten break-in time. The lid will still be snug, however this decreases the amount of break-in as well as makes it easier to use** I have a Canon remote Speedlite that eats batteries like crazy so I keep an extra set of rechargeable AA batteries in my camera bag. I wanted a case to keep them from shorting out and protect them from drops since I have clumsy hands. Plus high-capacity rechargeable batteries are more expensive as is the equipment they're going into, so I want to minimize the chances of them leaking or exploding by taking good care of them and not busting them up from drops. The case has wide walls all around the batteries including the top and bottom. The battery well and the case outer wall are a minimum 5.5mm apart, meaning the case would have to be completely destroyed for the batteries to take a direct hit. Be sure to limit Infill to no more than 20% 'Grid' style as the honeycomb effect will help absorb very hard impacts. If you print this and have time, please upload a pic to the "I Made One" tab. I love seeing my designs get printed! Thanks!
