Dragon Skull Hair Pin

This model is a remix from AngryAnteater's skull hair pin (https://www.thingiverse.com/thing:4978313). My friend were having problems with printing the original one. It has individual meshes and flipped normals inside the horn, which might have been the reason why some have had problems with the slicing and printing. I did fast fix for the normals, and combined all pieces into one solid model, so it should fix the problem.
