We designed and printed this 5' wide jet propellor for the entrance of an office building in Stamford, Connecticut. Over 300 print hours and 60+ parts (not including registration pins). Printed with Raise3d and Makerbot. The nose is sand blasted and the outer cowling is chromed, the rest are raw prints.
