This design didn't come from any tutorial or website! It was a fluid design, and i wasn't sure how it would end up until it was complete! i started by making a silver Icosahedron and then adding loops of 10 onto every point. The outer shell was simple enough to whip up. I just made the subunits a little larger than the ones used on the interior. I'm not sure of the exact magnet count, but i know it took almost 2 full Mandala sets!!!
