Targaryen sigil from Game of Thrones.
Stark.
Targaryen.
Greyjoy.
Tully.
Lannister.
Baratheon.
Arryn.
With the Prusa I3, you can print different layers with different colors. This sigil is made with that in mind. But I also added the model in different parts for multi extruders.*

Some models might not yet have multiple parts. However, you can split the "complete" model into several parts with "separate shells" found in most slicers.
I do intend to publish the other sigils, but it is a slow process (read my profile bio for more information).
