About this 3D model

UPDATE: I've learned a lot in the past few months and determined that just a little bit of built-in support would make this a much easier and quicker model to print. So, I've uploaded a new file for Cork Puppy that includes all necessary support and bits of rafting: cork_puppy_with_support.stl. Also, please check out my new thing, http://www.thingiverse.com/thing:317672, for a printable cork (allows for painting spots and for solid black for black labs) and accessories: bed, bone, bandanna and a bowl. Thanks! Following in the steps of recent designers, http://www.thingiverse.com/thing:215598 and http://www.thingiverse.com/thing:214766, I tried my hand at Tinkercad and cork_puppy is the result. I hope you like it!
