A Cow model for a 3d printer

thingiverse

I just discovered all this big thing of 3d print, Im so excited about the idea! I have no printer yet, but did this model some time ago and I hope somebody print it and I can see the photos of the real thing! Im not sure the model is printable, tell me what i got to have in mind to make it compatible if is not. Thanks so much. (*) English is not my mother language, excuse if I'm not easy to understand.
