This unique shape is a 30 sided die.
It's a twice zonohedrified icosahedron, an order 3 polyisohedron
. Though it actually has 90 sides, this design behaves much like a rhombic triacontahedron.
Note that this is a blank, so the faces will need to be numbered. For more information on unique dice shapes, see http://loki3.com/poly/fair-dice.html
