Tesla Model S Dashcam Mount

A device that clamps on to a Tesla Model S interior rearview mirror stem, and provides a flat mounting surface for a dashcam (it could also be used for radar detectors, etc.).
The camera end is just a solid tongue that you can drill through to hold the camera.
The clip is designed to hide the dashcam from the driver's point of view.

Note: the second image is upside-down, the camera hangs below it.
