This is a new fanduct with a build in holder for a dismanteled webcam as a nozzlecam. Withoud a cam you have a realy good visibillity of the nozzle. Original screws can be used. You will only need two additional 2,9x9,5mm sheet metal screws or something similar for the camswinger.
I used a Microsoft Lifecam for example. I also tried a bare 8€ webcam module from amazon which works absolutely flawlessly. To focus the cam just rotate the ring in front of the lens.
