I present to you, Chonkycell, the battery case.

Is it the most useful battery case? Doubtful.

The prettiest? Probably not.

But is it the chonkiest? Absolutely.

This absolute unit can hold up to seven AA or AAA batteries, depending on the version you print.

You can find the .3mf files that come prepared with the necessary color changes, as well as the .stl files in case you prefer to use your own settings.

I'd recommend you print everything with no supports, with the lid facing up if you have good bridging, or upside-down with supports if you don't. You may want to use a brim on the lid if your first layer is a bit finnicky and you print it upright.
