This is my homage to the movie with the seven symbols used to dial the first planet visited, Abydos.
To get the M16 Eagle Nebula printed on the model you need to order this in Full Color Sandstone otherwise it will just be the base model.
If you do order it in Full Color Sandstone please remember to seal it with a spray sealer as the sandstone ink is not waterproof.
It would be simpler to order this in the Glossy finish to have it protected from the start.
Note that this Mark2 version was updated with thicker walls on the ring and along the sides of the base based on recommendations from Shapeways. While I have not printed this version, my original model with the thinner walls that I used for testing is here
