This is a model of an akula class submarine made by Halcyon. I downloaded it from grabcad.com. I did some minor work with the model in solidworks to make this model 3D-printable, I removed the small attenas from the conning tower and I removed the screw, I also had to repair the .STL file as some parts would not slice well in Craftware.

With Halcyon's permission I may upload this on thinigverse so others can also print this beautifull looking submarine.

I printed mine vertically in 2 halves of exact 20cm each so the entire submarine is 40cm long, I used supports for the forward diving rudders and the tail
