Textured, using the Glimmar Steampunk texture pack, http://bit.ly/yh3ZWU. The latticework in this texture pack gives the model a more real feel. If I spent a bit more time, I'd substitute the lattice tile for the slabs tiles and get latticework throughout the model.
As it turns out, the printer doesn't do great on printing out latticework. The detail's nice on two sides, but the other two are half-there, half-missing.
