This is a model extracted from www.models-resource.com and smoothed out with MeshLab to increase triangle resolution.
*EDIT: The model had some problems with surfaces intersecting and result in bad print quality (mostly internal, but there were some external artifacts also). I used Blender to eliminate those internal surfaces and now the model is better than ever.
Enjoy and sorry if someone has already printed it.
