Description
When we travel we have a various number of AA and AAA batteries for various things.. they tend to get out of hand and mixed up in various bags.
I figured I could design a simple friction fit case that could hold 2, 4, 3 batteries either in a linear or 2x2 array.
The case has a top and a bottom and we use a simple heuristic: If the dimple is facing up the battery is charged.

Instructions
Print.. this works for the AA batteries we have, but depending on the tolerances of your 3d printer you may need to fiddle the radius of the batteries.
It is parametric so to generate a different holder you need to edit the scad file, select the right size and the right layout you want to use and generate away

Seems right for AAA. I can confirm R, can't confirm H right now. First print failed due to my experimental heated bed cover material (mylar). Tough and doesn't get torn up by my hotend, but not sticking well enough for tall Z prints. Back to Kapton. Printing another and I'll report back on the AAA
numbers. I'm going to want to make a few for CR123's also for my flashlights.

This is great! I made a couple of the 4x1 AA. It produced an airtight fit with AA Eneloops on a Replicator, the cells make a POP when extracted. A few minutes with a round file made it easier to extract, but still a friction fit.
I do not use SCAD. Could you post STLs for AAA? :-D
Sorry missed this comment.. I will post STL files for AAA's tonight when I get back home.
4 AA Eneloops. Printed on a Replicator with .2mm layer height, and 10% infill. The top is a friction fit that should not fall off.
