Hotend 30mm fan shroud

Human: Update August 8th, 2014: The Parsiotto version was giving me grief since the neck wasn't getting enough air, so I upgraded to V2, which has much better airflow despite being slightly bulkier and it just might get the job done. I had already updated the files following MrArrow1961's clever ideas on July 31st, 2014: The updates make it possible to print without the bridge in the middle now and may have boosted thermal efficiency. I created this shroud to shield your hotend from unwanted airflow. To meet diverse needs, I supplied two versions: one for magma and another for Parisotto - feel free to tweak them if needed! Print both halves of it first, then attach them securely around your hotend with a small amount of glue, only as much as is required - so you can quickly detach it if need be. To secure the fan in place, drill small holes on the bottom and use a flexible wire instead, I didn't have suitable screws so this is the best I could do for now, to be on the safe side, apply a few drops of superglue around the seams - that way they will be held firmly together.
