AA Battery Wall Dispenser Magazine

Another battery dispenser? Really?

Yes. There are several very good ones here, but there were a few criteria I wanted to satisfy that didn't come in a single thing. It would have taken more time to remix around them than to make a brand new one. Maybe your needs are the same as mine.

• holds more than 50 AA batteries
• optimized specifically for wall mounting
• extremely efficient on filament, no infill or support
• prints fast - mine finished in (barely) less than 12 hours on a slow Ender 3 Pro

My kids go through a lot of AA batteries. The only things I seem to use other batteries for are tiny flashlights and remotes (AAA) and smoke detectors (9v). For those reasons, I'll eventually make a complimentary design for AAA and 9v, but they will probably not be dimensionally or even proportionally the same.

This thing is pretty tall at 200mm, and it starts out as 2 parts until they come together a short ways up. If you have any questions about whether you should use a brim, use a brim.

Walls are 1.6mm thick, so a .4mm nozzle with bog standard Cura settings will print perfectly stable and solid without infill. The slope is 45 degrees; you can safely print without supports and it should be fine.

I found that the bottom screws were not necessary, but they may contribute to stability as the box empties and becomes lighter.
