Fan vent with direct air blow on printed surface , no air will blow to the nozzle

Hey there!
First off all let me tell you that I'm starting an youtube channel where you can learn Matlab. Matlab is a very powerful engineering tool widely used in the present day. Please, if you like this part it would be very helpfull if you subscribed to my channel!
Thank you!

Part information bellow,
NEW VERSION:
As many users have requested requested, the tip is now inclined so the air blows directly bellow de nozzle;
A full sleeve has been added to minimize the airflow loss beetween this part and the blower;
Better dimentions;
I've included the gcode I used on my CR-10 to print this part (for PLA only) in the file section as well as the STL of the new version.
This is an easy to mount cooling mod for the Creality CR-10, the other CR series and the Ender 3.
This mod redirects the fan air flow directly to the tip of the nozzle without being too big or obstructive. If you are looking for the best print quality this is definitely a must for your Creality…
