Tevo Tarantula - Hexagon hotend 40mm fan shroud

This is a Fan shroud for the Tevo Tarantula. This is designed to fit a hexagon all metal hot end. This works with the 20x40 Modular Carriage http://www.thingiverse.com/thing:1839201
Note there is a small triangular piece I have also designed to fit the modular carriage to get it in closer to the carriage. Look it up in my things. This design uses a 40mm fan to cool the heat break and the model being printed by splitting the air to both locations. This design was inspired by LPA Fan ducts f
