This is just the piece that connects to the Z rail and allows you to use the original parts from the author to mount your Creality Box 2.0 camera on the Z rail. I am not a modeler and this took a while to get to this point. I can verify it works for me.
The author remixed this model.
This is mount with an interference fit for the Ender 3 Neo rail. The rest is original from the primary author which you will need the pin, screw, and mount for the camera.
