Simple coaster with Seattle Seahawks logo etched in.
I added 2 new files. One (seattle.stl) so that you can have 2 colors (green base, white outlines, grey, and blue). The other (seattle 12.stl) is the 12th man logo!
seattle: green @4.8mm
Designed coaster using 123D design then took Seahawks logo and etched it out in center.
In order to make multicolor, I watched the print in Pronterface and when it started the layer with the base of the inner etching, I paused it, changed colors and resumed. Once it completed the base of the etching and the first row above it (noted by seeing the outline of the etching), I paused again and changed back to the original color and resumed.
