AA Battery Case for 3 Double-A Batteries

thingiverse

I needed a rugged storage case for my 3 AA batteries, so made some quick tweaks to my existing <a href="https://www.thingiverse.com/thing:3527155" target="_blank">3AAA Battery Box</a> and voilà! Discovered that I had to add .05 mm to the clearance around the batteries for smooth sliding action - a crucial adjustment compared to the AAA batteries. Moreover, the width of the sidewalls plays a significant role in achieving a clean multiple of the extrusion width to get the ideal friction fit for the lid. Here is the final result of my iterative process to perfect it. The lid stays securely in place, and you can stash it safely in your gear bag, boat, car glove box, or anywhere else you need it. This print was done in PETG, but it works equally well in PLA.
