The head of my Dimetrodon, modified for STL printout.

Some assembly required. Video assembly guide included (in AVI).

Note 1: The assembly guide to this model, as well as the guides to all my other models that require some assembly, are available to view and critique on Youtube. So far, these include my Dilophosaurus, Eolambia, Short-faced Bear, Uintatherium, and Dimetrodon. To view these assembly guides, in the Youtube search box, enter the name of the model, then the keywords "assembly guide." For the Short-faced Bear, you may also use the word "arctodus."

Note 2: I've been having particular problems with the Blender OpenGL renderer this time, so I had to use the camera to render the pictures of the model.
