Kort nozzle for 50 mm propeller

Model of Kort nozzle used on working boats ( i.e. tugs, research vessels...).
I modeled it using online pictures, and some basic information on the shapes of these things.
The model itself is made of 3 parts, Korth 1 is the main body of the nozzle, Korth 2 is the rudder mount and the Rudder. I printed the model from PET with the Korth 1 laying on its face and the rudder oriented upside-down. The print was done using 0.4 mm nozzle and 0.15 mm z step. The infill was set to "Archimedean Chords"
