I designed this for my Rat Rig V-Core 3. It's not the best camera or mount for this application, but it's Fine™ for now. The view is a bit narrow, and high accelerations cause the camera to shake a bit. Also, the auto-focus is thrown off by the toolhead movement sometimes, so you may want to consider switching to manual focus.
You'll need to remove the plastic mesh cover from the front of the camera (it's glued on and easily removed), and remove most of the guts of the camera from the enclosure before you can access the 4 screws that hold the existing mount on.
The pivot uses a pair of M3 screws and nuts. The base uses an M5 screw and T-nut for the extrusion.
