40mm Fan Duct for 3DR Simple J-Head End Effector

This is a fan duct I designed to fit my J-Head end effector on my 3DR simple. The inspiration for this thing came from http://www.thingiverse.com/thing:209423.

This fan shroud is designed/angled to provide direct cooling air to the cooling flutes of a J-Head. Cooling air is recommended for cooling of J-Head hot ends when printing with PLA to prevent jams in the upper part of the hotend.

You'll need to print the updated J-Head Locking Plate that's part of this thing as well. The locking plate here is for a j-head groove mount thickness of 5.8mm. Let me know if you need a different thickness. My Tridprinting.com J-Head groove is thinner, for instance and will not work with this design.
