Improved Holder for Height Adjustable Fan Duct (Zonestar P802Q)

I really like the design of rumlyne [1]. The benefit of this design is, that you can easily remove the ring-shaped fan duct (e.g. if you print ABS and don't need a fan duct or if you are levelling the bed of the printer) Unfortunately you always have to remove the fan to adjust the height. That's why I created a version of a holder with adjusting screws from above. Further more I added a spacer for my autolevel sensor.

Variation to rumlyne-design:
Part "Halterung"
- height adjusting screws
