--> Edit 2015-10-23: I added a lower poly version (OwlVoronoiSupportless) that is reoriented/plane cut before editing and making a Voronoi style pattern - it should be able to be printed without support structures. I curved the tail a bit and modeled it so it isn't overhanging as much as the other version. Enjoy! <--

Wanted to try another voronoi like pattern with MeshMixer (http://www.meshmixer.com).
I reduced the original mesh, cut the bottom with plane cut (no fill) and reduced some spots in the mesh. Then I made a pattern from the edges of the triangles to make a new wireframe.
