Fan Duct for Ultimaker

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.
