This is a model of Earth made of a sphere with two displacement maps. A specular map displaces the land & ice masses above the oceans. A topography map adds texture to the land. This exaggerates the texture more than a topography map alone. It was inspired by http://www.thingiverse.com/thing:14070 and http://www.thingiverse.com/thing:11660 Now available on Github: https://github.com/bld/Textured-EarthThe Blender file contains the 1K specular and bump maps from: http://planetpixelemporium.com/earth.htmlTo wrap your own displacement map on a sphere, it needs a UV map. Select the sphere. Go to mesh edit mode (Tab). Change the view to "Front" (numpad 1). Select Mesh -> UV Unwrap -> Sphere Projection. In the displacement modifier, set the "Texture Coordinate" to "UV".I didn't intend to print this model by itself. I used it in another project.
