I am trying to figure out how to mathematically represent the MMA 9 Spikey in order to send to a 3D printer.

According to this page, " In particular, spikeys for version 2 and up are based on a hyperbolic dodecahedron with embellishments rather than a cumulated icosahedron."

How might I represent these "embellishments?" An .stl file has been generated (and is here, for all interested) of a rhombic hexecontahedron. This, however, is the farthest I have progressed.

Any help would be appreciated.

    $\begingroup$ Michael Trott wrote a blogpost on making the Mathematica 6 spikey... that should serve as a good starting point for you. $\endgroup$ – rm -rf Mar 4 '14 at 5:03
  • $\begingroup$ Thanks for reference! I've seen it, but am really trying to get that distinctive "9" look. I will be sure to look at it again, though. $\endgroup$ – Qu0rk Mar 4 '14 at 5:10

    $\begingroup$ That's going to be a lot harder... it's probably Trott's secret sauce. $\endgroup$ – rm -rf Mar 4 '14 at 5:13
