18650 battery holder for headlamp torch

thingiverse

This is a battery holder designed to replace the standard one that utilized three AAA batteries. It's built around a generic 18650 battery holder and a TP4056 protection/charge board. This particular model features a 0.1mm gap between the lid and base, if you'd like you can modify it in the sldprt. Little to no attention was given to details, it was done within a few hours. I would be thrilled to see your remixes.
