Fan Shroud for Prusa i3 Jhead on Greg Wades Extruder

After looking around for a good Jhead cooling shroud for my Prusa i3 which runs the Greg Wades Extruder i decided to give a shot at designing my own 40mm Fan Shroud. The main reason is that when printing with ABS my last fan setup affected the prints. With this no airflow affects the prints. huge improvement...
