This is a Hueforge STL of an Charmander/Charizard Evolution I found on the internet that I liked.  I take no ownership claims of the artwork itself.  I just ran it through Hueforge to get the STL and instructions.

The Model is 200x162.94mm in size
You may print at higher layer heights below the Min Depth of 0.48mm
The Max Depth is 2.2mm and the Actual Depth is 2.2mm
