Next question,
Has anybody ever come across a Triacontahedron box that opens with 5 fingers each hand?? I stumbled on it few years ago, and so far I have asked many puzzlers, and none have seen it.
As with  Stewart Coffin's Pennyhedron that opens with 3 fingers, it is logical that a 10 piece circumference run of the Triacontahedron can split in two 5 piece halves.
Variations of wood turned spheres , rugby balls, and easter eggs have been made, now working on a  wood turned 6 wood version. The latest the Spherical Truncated Tricontahedron at the IPP28, along with the soccer ball (spherical truncated Icosahedron) for comparision
Sorry for the big mouthfulls of words,hence I called it the Chinnyhedron, till a puzzler says otherwise.
I would love feedback info on this, I think its a first,I'd send a pic but I don't know how,,,,,,Stephen Chin

I can definitely see what you are describing, as I have played around with many different versions of triacontrahedrons.  I have thought of using these "chinnyhedron" to make up a "chinnynut" or modified peanut puzzle.  But the labor would be enormous.

I have also translated Stewart's Sphinx puzzle onto the surface of a triacontrahedron.  This is one I hope to make a batch of soon.

I have also thought of adding pieces to the outside of any of these designs to make a 30 pointed star shape.  But again, so much labor would be involved in such a puzzle.
