The files used by most 3d printers have been uploaded to thingiverse at (http://www.thingiverse.com/thing:408099/#files). The files were exported from blender format to stl. Please message me if anyone needs the original blender project files. I used Slic3r version 1.1.6 to generate gcode from these files, and Repetier-Host 0.85c to load the gcode and print these on my Solidoodle 2.
