This is Kalecgos from the game World of Warcraft or from the Warcraft universe.

This is my first ever design. I made the model starting from the "Red Dragon" model but altered the whole look of it with Meshmixer.

I uploaded the whole model in one file too, but I wouldn't encourage printing in in one piece (also due to changes to the final look of the model, i made it by combining the parts together as a tepmorary solution).
