Moar liek this.I made a 30 piece dodecahedron modular similar to this earlier today. There was one I made a long time ago that was similar, but each unit was completely parallel on a plan crossing the center of the ball, and there were both pentagons and small triangles for openings. Each unit piece looked like a triangle with wings. If anyone can help me find the instructions again, I'll love you long time.
I don't know what you made, but maybe this will help:http://kahuna.merrimack.edu/~thull/phzig/phzig.html
