This is a model or a Pre-I SSN688 Class (Los Angeles Class) fast attack sub. The outline for the model came from the 688 Wiki page so it's not very accurate and is missing a LOT of details.
I have uploaded a complete hull model as well as sectioned pieces if you are space constrained on your printer. I made one about 2 ft long on a Makerbot Replicator 2X using .3mm layer height, 10% infill and 2 perimeters. I glued the sections together with an acetone/ABS paste-like slurry.
I used http://www.thingiverse.com/thing:287026 as a propeller. I merged the tailcone with the propeller and printed them as one piece.
The model was created in SW2013.
