An original piece designed in multiple parts. The horns, teeth, tusks and flairs are all individual parts that have been separated and oriented in the STL file.
Supports are highly recomended and Filing or sanding may be required to get the pieces to fit precisely but on the whole assembly should be easy with a spot of glue as it follows a simple peg and hole design format.
The teeth and horns are probably the hardest to print as they are tall and or have relatively little surface area. Unless you are fine with printing them flat and sanding the daylights out of them.
