The Maker Select V2 camera mount had quite a few versions, some using an endoscope camera, and some using a large squirrel cage fan with a tube down to the hotend. 

While functional, I'm not really happy with it so I'm doing it over. I think if it's simpler more will be inclined to try it. 

I'm also working on an "installable package, separating the Octprint plugin from everything else. Since the pizero filesystem is accessible on the 3B+ , I intend to move everything else to the Pizero image. Then you would just need the plugin, image, and a little setup on the 3B+ to serve the image.
