Remixed quite inelegantly from Original Prusa : https://www.prusa3d.com/prusa-i3-printable-parts/
I know there are some residuals from original botched model but overall this works as intended and I believe it is better than what it was.
The space between motor and fan should be 2mm in this version.
I have previous design which needed me to flip the motor (seen on the picture attached), but it should not be the case in version. No Firmware changes require, the fan goes to the same port that radiator 30mm fan.
