Recently I needed some basic battery packs for 3 AAs but could not find any that were both simple and robust enough to fit my needs, so I decided to make my own. These packs will allow you to wire 3 AA batteries in series with just a 2 mm wire and rubber bands.
Two types are included: one symmetrical (pack A), and another that is a bit less wide (pack B). Functionally however, they are identical.
To put them together, first thread some 2mm wire through the holes and into the grooves and make sure to deform them solidly into place. Then place the center pillar into the bottom hole, slide the batteries in place (minding the polarity of course). Afterwards, attach the top (with pack A, make sure to rotate it correctly to prevent any short circuits). And lastly, put on some strong rubber bands in the way pictured to hold it all securely in place.
All models have been tested on an Ender 5 Pro (PLA, 0.2mm, 100% infill for pillars, 20% for top and bottom).
