About this 3D model

Fan Duct for the 'original' 50mm Ultimaker fan, with donut-shaped cooling area around the nozzle. This is a derivative of Geo Hagen's well designed Fan Duct (www.thingiverse.com/thing:16624) and Owen's great Fan Duct (www.thingiverse.com/thing:13625) Printed in PLA, no support or raft needed. 20120219 Added a lower resolution STL file with less polygons.
