Ok, I added Tully and Arryn. Haven't tried them out yet, but you should get a perfect Arryn, and 3 layers of Tully. I tried Martell but it's going to take some work. My computer is having trouble turning the mesh into an .stl ; martell sigil has about 30,000 facets.
I'll work on the Tyrell sigil soon. See if I can get more layers
