Minimalistic double AA battery holder
youmagine
A friend of mine called out my previous revolver-like battery holder design (https://www.youmagine.com/designs/sealable-aa-battery-box), so I chose to create a more minimalist version just for him. I also documented the entire design process. Since the initial design, I fine-tuned some parameters, ensuring that this new device securely and safely holds the batteries. The print with 0.2 mm layer height and 20% infill requires only about 7.5 g of filament (which is roughly 920 mm from its 2.85 diameter counterpart), making it perfect for utilizing leftover filament. Update: Following defuzz's suggestion, I created a second, subtitled screencast to make the process easier to understand:
