A picture of a 3D printing of  the USS Grandeur logo.   The 3D print was created using Blender, an open source 3D modeling, rendering, and animation software tool, which you may download for free from Blender.Org.  The 3D printer prints a backing called a raft for the 3D model to print on.  The raft holds the model stable while it prints.  I left the raft on this model because the gold leaves around the outside are loose.
