About this 3D model

Because narwhals are awesome! Designed to match the excellent [Zookins](http://www.thingiverse.com/thing:31313) set. This is now collected with other animals in a similar style under [Animal napkin rings](http://www.thingiverse.com/thing:1238843). **Updated ten years later:** Never noticed that the normals were flpped, and more recent software doesn't like that. Fixed.
