About this 3D model

A while ago I came across this piece of concept art of a steampunk-ish looking sub. Didn't know until later it was actually a concept design for the Disney animation movie "Atlantis". I like it so much, I thought it would fun to model it in 3D. My personal challenge was to do some hard-surface modeling entirely in Zbrush. This was pre-4r7 ;-) Anyway, happy printing and putting it together! Shouldn't be that hard, just some glue and check the renders to see where what goes. It's a pretty symmetrical model so this should be easy.
