This is a cold shoe mount for an M5StickC or M5StickCPLUS. This can be used with any camera shoe mount. Theres 2 version, one with the cold shoe screw on the bottom for it to face out, as well as a cold shoe screw on the back to face up. (I've found that the back option may be a better for you if running the camera handheld) I personally use them with Tally Arbiter to provide production switcher tally display to the camera ops at our church.

The author remixed this model.
I removed the screw hole mounts off the side of the original model. Added a ¼-20 threaded receiver nut on the bottom for the cold shoe attachment. I also, removed some of the tip of the mount to expose more of the internal red led because its used in tally arbiters operation.
