Here's a classic star for Christmas day.
To build your own, you'll need somehow to build a "phi bar" - one that is longer
than a regular bar by the golden ratio.
I used regular 1/2" spheres here, and made elongated bars with 1/4" cylinder magnets, and
short Supermag bars.
It's called the great stellated dodecahedron, because its made from 12 large star-shaped pieces,
all intersecting each other.
Merry Christmas magnetic modelers.
