I really like the original design of this for the Logitech C920. The hinge works great and feels solid. Unfortunately my webcam, the Logitech C930e, is ever so slightly different. It could have fit well enough, but I can't leave well enough alone. I needed to make some tiny modifications to make it more snug.
-I took away the roundedness of the the inside corners.
-The front top corner of my webcam also isn't a perfect 90 degrees, so I've adjusted for that as well.
