I bought an SQ8 mini camera. It makes great photos but is a problem to mount on my camera holder. I came up with this little device that serves two purposes. When this camera is charging or is being used, the lithium battery gets hot. This aluminum block serves as a heat sink. I tapped a 1/4 20 hole in the block to mount on a tripod, head band etc, The 1/8" slot lets you see the little camera light on back of the camera. Works great.
