This is a spherical design exhibiting ten, six and four pointed stars. This pattern is derived from a truncated icosidodecahedron and printed in 20 interlocking pieces. The pieces are pretty loose but become more rigid when complete. This particular model has never been printed because I first ordered 2 pieces to see how they'd fit and then went ahead and ordered 18 more to finish my prototype. This model has all 20 pieces that can be pieced around a lamp and glued for stability.
