If you use rechargeable batteries, you will need a place to keep them when they are not in use. This holder/carrier will allow you to toss them into a bag or drawer without worrying that they will short against something metal. They are designed to be quick to print and use minimal material.
This is a remix of my original battery holders. With this remix I'm addressing a problem with the original version where the batteries in the end slots were difficult to insert and remove. A small taper at the bottom also gives more flexibility, protecting the batteries and resisting breakage if the holder is dropped.
Works well when printed in a transparent/translucent filament so you can see which batteries are inside.
PETG recommended for flexibility and impact resistance.
Can be printed in vase mode.
