Nozzle Fan Duct

My First project,
its easy to print and has a very good Airflow.
Fits Perfect for my AnetA8, my nozzle tip is around 0.5mm lower than the FanDuct.
The Airflow sourrounds the Nozzle but dosent hit it directly.
Four AirTubes (3x4mm), hit the Print from different angles.
I did some test with smoke to see what the air is doing when it hits the print bed, lets say it looked weird,the pics i took dosent captured the smoke :(

Pro... High effective, Low noise generation, low air flow resist
