Be careful, he has very sharp teeth!

My dragon head is about 12cm but if you print it smaller I think then they won't see much detail.

But if you print it bigger, it will be even more scary :)

And for fun, his jaw moves in clubs so he can open and close his mouth.

The assembly instructions are very simple: first glue the coupling to one of the halves, put the glue on the same side, put on the lower jaw and put on the other half. The coupling therefore helps keep both halves straight during gluing :)
