I printed this T-Rex head with support for the back of the jaw and the upper teeth. The model printed fine for me without support going all the way up to the chin. 

For similar models see my Collection of Animal Heads/Busts that I have designed or remixed. All of these designs use the same bracket to mount, making them interchangeable.

Mounting Options:

• Bracket for Wall Mountings - mounts firmly to wall with one screw (use top hole).
• Modular Stand - print and press together a stand to put this on a table or desk.
• I've also included a small slot, so this can be hung on a wall with a nail.
