At first this puzzle seems to be a member of the radiolarian series but it was designed by a different person after the first three radiolarians. It differs from its cousins by its cutting depth.
Just like the other face turning Icosahedra, the DeFTI can jumble.
In 2012 Jason Smith presented another design of this puzzle he called "Radiolarian 4" because it fits into his series of face turning icosahedra.
Piece type signature: DC2[F3 C4 X9 T12][F3]

For the first three years this puzzle was available only from a 3D printing service. Beginning with 2013 a mass produced version is sold under the name "Eitan's Star".
