This is a remixed version of the great model made by SilentWoof on thingiverse with a few extra bits included.
I've reshaped the main mount body to provide a cleaner look with less sharp corners.
The optional ball joint is remixed from FedorSosnin on thingiverse and can be fixed to the bracket using a metal screw and then used to provide an adjustable pivot point for the webcam.
The Cam Screw from AxxAxx on thingiverse is pretty fragile due to the print orientation so don't over tighten.
