Stark sigil from Game of Thrones.
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).
The first 2mm is supposed to be printed in white. I used 0.2 layers.
For the details I used 0.1 layers.
2.0 - 2.2 grey.
2.2 - 2.4 black
For Prusa I3 ColorPrint users: You want a color change at 2.1 and 2.3 for these settings,.
If you don't know how to use different layer heights, I would recommend 0.1 All the way.
Use as a coaster (only cold drinks I think)? I would think a layer or two of clear lack would be a nice addition.
