I wanted a AAA battery holder that could print in vase mode and and have enough flexibility to accommodate variation in battery diameter, so I designed this.

Designed to print with:

Spiral vase mode
Nozzle diameter: 0.4mm
Wall thickness: 0.6mm
Layer height: 0.2 mm
Bottom shell layers: 5
Wall generator: Arachne
Skirt loops: 1

If you use these settings, the first 5 layers will print in regular mode, and then will switch to vase mode for remaining layers. This is done to print the bottom support/frame portion that can't be printed in vase mode.
