Titan Submersible

This is the Titan submersible that they use to take tourists down to the Titanic. It can dive to a depth of over 2 miles and carries 5 people. I made this design kind of quick, I couldn't find any schematics of the Titan so I made it based on photographs. I haven't tried to print it yet so I have no settings for that. I imagine I will cut it in half for printing.
