PLA cooling fan for a J-head Hotend

Tried to find a cooling fan that cooled both the hotend and the PLA using just one 40mm fan. Couldn't find one I liked, so built my own. Took far to long building this in sketchup, Just painful. But got there.

The fan holder diverts 20% of the air from the fan, to cools down the print, without cooling down the hotend itself.
