The Velociraptor Head is a little more complex to print than many of my other animal heads because the teeth require support. You will probably also want support for the back of the jaw, but this model printed fine for me without support going all the way up to the chin. When slicing this model make sure the teeth are connected to the mouth properly (the model overlaps itself in those locations).
This can be mounted firmly to the wall using Thing 3865583 - Bracket for Wall Mountings. The bracket has room for two screws, but I've found that using the top screw hole only is sufficient. I've also added a small slot, so this can also be hung with just a nail if you prefer.
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 to the wall.
If you print one, please consider posting a make!
