18650 Battery endcaps (single and double)

These work great with a simple hairband and are designed to be a nice fit over the ends of the battery. If they are a little tight run a piece of sandpaper over the inside until they fit well.

Print two - one for each end. You can use the single for one battery or the double if you need two at a time!

Great to carrying packs/batteries safely without the worry of something shorting the ends..
