Custom fan shroud for Sunhokey prusa i3 2015

I designed these simple fan shrouds for my sunhokey prusa i3. This fan shroud will be mounted on the extruder part which I remixed. They blow air on the printed parts for faster cooling. This will prevent the plastic from warping. Print two of both parts to have both sides of the print cooled.
This design needs support material to print!!!
It will fit a standard blower fan you can buy from aliExpress or ebay.
I have also attached the Fusion360 file.
