This will work to keep a typical Action camera pretty much anywhere you can screw into but was designed with an RC plane in mind, hence the name on the side of the model.

The Nano Talon EVO used to come with a balsa mount for a downward facing GoPro/Action cam, but it seems to be sold separately for $20 nowadays. This model should do roughly the same thing in the same way. The dimensions here are based on the Akaso EK7000 action cam, so make sure it fits your camera.

You'll need the screw to secure this and a small rubber band to secure the camera in the mount.

The .STL and .SLDPRT are available. I recommend printing vertically but any orientation will work.
