This is another rhombus to add to the basic set of polypanel shapes (see below for details of other polypanel rhombuses). The lengths of the diagonals of this 'golden' rhombus are in the golden ratio (1:~1.618).
You can make some interesting polyhedra out of golden rhombuses including a rhombic triacontahedron with 30 faces (which ends up being about 15 cm in diameter), and a rhombic hexecontahedron with 60 faces (about 21 cm in diameter).
Check out the Golden Rhombus article on wikipedia.
I've made three different variants of the Golden Rhombus polypanel. The ones with the center hole use less filament and are compatible with my Polypanel Face-Snap System (#PPFSS), which means you can snap various standard-sized attachments into them.
OTHER POLYPANEL RHOMBUSES:
If you're interested, I've also made some other polypanel rhombuses that have different internal angles including:
* The Root-Two Rhombus, which you can use to construct a rhombic dodecahedron. It has diagonals in the ratio 1:√2 and internal angles of approximately 70.5 and 109.5 degrees.
* The rhombuses used in my Polypanel Penrose Puzzle. One has internal angles of exactly 72 and 108 degrees, while the other has internal angles of exactly 36 and 144 degrees.
One of the original polypanel shapes designed by Devin Montes is also a rhombus. Devin's rhombus has internal angles of 60 and 120 degrees.
And if you have suggestions for any other rhombus varieties, let me know!
