Summary
A remix form the nicely designed Logitech Webcam mount. This one is made for the C910 / C920 which you can tighten with a screw with a M6 bolt directly in the simrig. It's adjustable in height so it's usable for different monitor sizes (although you stil can use a mag mount, but the hole in the base is larger to fit a M6 bolt).
The author remixed this model.
