18650 Battery Spacer 23mm Outer Diameter

thingiverse

I created a custom adapter to fit an 18650 battery in my "as seen on TV" flashlight that normally uses three AAA batteries for power. I engineered it so it's not a full sleeve, and it requires less filament than a full spacer. In my specific flashlight, this design keeps the battery securely in place without moving around inside, and I've also avoided any risk of the battery getting stuck in the body. The adapter is designed to print without supports, and I added a circular base for stability. To ensure a successful print, place this base flat on your bed. Once printed, it snaps off easily! Please be aware that swapping batteries can pose some risks, so do your research and proceed at your own risk.
