This mount fits the body of the Logitech C910 once the original mounting hardware is removed. The mount fits over the back of the camera and can be secured into place using a M4x22 bolt. There is also a flange that the camera fits into on the mount, this limits X/Y jitter quite a bit when the camera moves. Between this and the bolt the camera stays pretty darn secure.I used the mount to attach the camera to a "TERTIAL Work Lamp" from IKEA which runs around $9. It makes a great camera jig and unobtrusive desk mount for recording Makerbot prints or anything else really.
