Updated Improved Fan Shroud Remix

Updated some things so this fan shroud would work better to fit my printer:

Opened up and improved alignment for the hot end clearance
Smoothed edges inside and out
Elongated the shroud so that the fan sits on the other side of the y-arm
Added a cut out in the front to better see the nozzle
Pushed the bottom up a little so that there is more clearance for the bed/part
