Summary

After the popularity of the Reddit post I did http://imgur.com/a/yrEt3
a lot of people wanted access to the files I used. Here they are.
The only thing I did differently was chop the two sides of the faces (right side of face) and (left side of face) further into two equal sized halves.. so 4 parts total. Unfortunately I couldn't find one of the files and I didn't want to go through the whole cutting process again for those two files.
I would put one of the "right or left side of face" files into your slicer and scale it up to your max bed size. Then just remember that scale value because that's the same value you will use to scale the other parts for printing! I scaled my dragon up to x11 on a 8" prusa i3. You will have to slice the face files up to get that big I think. Also I used Slic3r to break up the neck/horn stl file into multiple parts then printed the horns separately and positioned them so they would print.
I also included just the head if you want to cut it up yourselves.

Its a big print job... good luck!
