I required a more adjustable mount for a Logitech 910 HD webcam. To attach the camera I take off the plate in the foot as shown and attach the cam with 2x M2 12mm screws to the slider. The mount fits beneath the heated bed and you could cut M3 threads into it to attach it more securely. I just slip it on if needed. Another M4 screw and nut fixes the slider with the cam at the desired distance to the print bed.
