Whale's teeth are highly prized in the Pacific Rim, particularly by whales who like to use them to munch lunch. Islanders incorporate them into items of ritual significance, generally obtaining them these days from expired whales washed up on the beach.

This comes out pretty tall. The tallest I could print was 105mm, but scale to suit your printer.
The AoI file includes the solid tooth, so you can manipulate it to produce obscure drinking horns, vampire whale masks for hallow'een etc. if you wish.
