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.
