C270 Camera mount for AnyCubic Mega Zero

This is a mount for the Logitech C270 camera for AnyCubic Mega Zero. It mounts around the X-axis stepper motor so will stay in the same relative location as the print grows vertically.

This remix does two main things:
* It flips the image so its ready for installation.
* The angled joint near the camera mount is reworked so be stronger.

The C270 should be in 16:9 for best results. It may also benefit from a manual focus mod, depending on the size of the items being printed.

This uses the original M3 screws when mounting on the printer.
