GoPro Bubble Level

This widget holds a bubble level, to aid in leveling GoPro cameras. The bubble level itself is one I purchased on AliExpress for $1.25. There are many others of this sort on AliExpress, and the design can be easily adapted to most of them. The holder for this consists simply of a 2-tang and an opposing 3-tang GoPro attach points so that this can be put just under the camera.

See the pdf description in the files section for more details and information.
