3D Printed USA Geography Wall Art - Easy Filament Change

This is a remix of https://www.printables.com/model/519719-3d-printed-usa-geography-wall-art I modified it so that the word art is proud of the backer so that you can easily add a filament change at layer height for a multi-color print.  The print shown is scaled to 30% in the X & Y with no scaling in Z.
