The original designer did a fantastic job with the geometry of the mount and mounting mechanism, I however wanted a more secure way to mount the webcam to the mount. As we all know cameras use a standard 1/4-20 bolt, so that's exactly what I made, this screw works with most camera bolt mounts. I also made a hinge slot connector that allows the hinge to be assembled without the use of bolts, this part is called the hinge slot pin trial 2 and is meant to connect the base and arm and works just like a pin.
I suggest that you go with as high of a resolution as you can go, this will make the bolt stronger and more accurate. I printed at a 0.15 layer height and went a little slower on the speeds, also use 80% infill or max out walls or get close to filling the entire thing, this will make it stronger and will not use a significant amount of plastic
Don't over torque the screw, at the end of the day it is a plastic component made on a 3d printer, especially if you didn't use the necessary infill as mentioned earlier.
