Ender 3 Fan cooler MOd

Just got my new Ender 3 and I love it. I did small modification to the stock Fan duct, It improved the results for me- Hope you like it too..

P.S- just rotate it as shown in the print-screen in Cura.

Edit: Added V2/V3 with small changes to fit more freely.
Edit2: Added V6 -Improved Version with better design and cooling.
