The author remixed this model.
It was already a great model, but with my webcam I felt it had a slight bit of weight that would make it warp slightly. So I modified it adding braces to support the camera and prevent it flexing/warping/wobbling during any future prints. I raised the camera mount part up slightly as my webcam would hit the touch screen and kinda still does, but also gives more of a view of the buildplate rather than a complete side on view.
As with the original, it will require 2 M4 Screws, either 14mm or 10mm will work, I think I used 14, 4 M4 Washers (To protect the print and printer frame) and 2 M4 Nuts. The camera mount will need a 1/4in screw, length is whatever best fits your camera.
Note: I'm not sure that if you mirror this model to be able to attach it to the other side of the gantry, that it'll fit properly. The holes in the frame seem symmetrical but the housing that covers the gear holding the belt is a different size to the belt tensioner. It appears to be smaller so if it does fit feel free to confirm.
