About this 3D model

Just finished to design it in order to fit with the excellent dual extruder done by Riku Rusanen : http://www.thingiverse.com/thing:201184 The thickness of the duct has been resized to 1.5 mm in order to ease the building of the walls. Overweight should be unimportant. IMPORTANT ! choose the fan duct related to the extruder you' ll use to print that duct: _ fan duct 1.4 to be printed with 0.4 extruder _Fan duct 1.5 to be printed with 0.5 extruder Prévu pour l' excellent extrudeur de Riku Rusanen : http://www.thingiverse.com/thing:201184. L' épaisseur de la buse a été augmentée en vue de faciliter l' impression. Le surpoids devrait être négligeable.
