Update: I've added the Fusion 360 model. Hope you find it useful.

For years I've wanted a narwhal tusk. Since getting a real one is not something that a person can actually do I decided to draw one. I didn't know what I was getting myself into. This thing ended up being a bear to draw.

That being said. It's full size, over 8 feet (2.4 meters) long and almost 4 inches (100 mm) wide at the base. Good luck printing this one. When I get around to it I'll try upload the model in pieces so it can be printed in bits and stuck together afterwards.
