Carved from a 2"x6"x6" piece of Amazakoue wood. It has three holes, making a genus 3 surface. The raised edges form three separate curves, each of which pass through a pair of holes. It is called a Genus 3 Triple Link. It was inspired by a surface made by another artist on Shapeways.com, but it is not hollow since it was carved from one piece of wood.
