Simple universal E3d double fan cooler

Hopefully this will fit most printers. The heat sink mount snaps on and will hold a 30mm fan. A 40mm fan is needed for the duct.

Right now I am using this on my RostockMax without stand offs.

a couple of nuts are needed to mount the duct fan, I plan on changing this to make it simpler.

***UPDATE***
Version two doesn't require nuts, simply thread the holes to mount. Also, I've lowered the arms to give more clearance for larger fans.
