This is my idea of a easy solution to add a ring camera to your z gantry that will follow the nozzle so you can monitor prints without having to upgrade boards and firmware or modifying the printer . Im not a great modeler so this is about as good as i could design. Feel free to use for your purposes. Printed on Ender 3-dont know version.

Im sure it could be modified for other machines but this editiration uses the same screw the top z gantry wheel uses.

Just take off the nut, sle the mount on with some double sided tape on the bottom for good measure, then reinstall nut and tighten it snug.
