I wanted a simple to print strong battery holder for my rechargeable batteries. This design holds many variants, for storing AA, AAA, 9V and 18650 batteries.

They are designed to be printed in spiral vase mode only. They are very fast to print and use very little filament

It is important that these are printed with the following settings to get a successful print:

• Spiral Vase mode.
• Layer height 0.20mm (Including the first layer!).
• Base layers set to 10
• External perimeter width to 0.8mm.

These could be printed in any material, I used PLA and PETG.

Please use the provided 3MF print profiles with all these settings already applied, just change material to suit what you have,
