This is a friction fit tracker mount for putting an HTC Vive Tracker on a Logitech C920, C922 or C930e webcam. It will allow for the full tilt of the webcam on its base.
The mount holds on pretty tight by itself, but you can always add a little bit of double-sided tape to the top of your webcam to add that little bit of extra grip.
You will need a 1/2 inch 1/4x20 bolt or screw to attach the Vive tracker to the mount. This is a standard camera mount thread.
23-8-2018 Added an untested version of the mount with a nut slot to keep the screw in place and cut holes for the microphones built into the camera. If you print this version please let me know of any problems with it. I do not have a way to test for quite some time.
