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 cotrained on your printer. I made one about 2 ft long on a Makerbot Replicator 2X using .3mm layer height, 10% infill and 2 perimete. I glued the sectio together with an acetone/ABS paste-like slurry. I used as a propeller. I merged the tailcone with the propeller and printed them as one piece. The model was created in SW2013.
