Icosahedron/Dodecahedron based puzzle ball

# 75 mm Puzzle Ball **Made of 60 identical, quadrilateral tiles.** The ball is based on the [regular icosahedron](https://en.wikipedia.org/wiki/Regular_icosahedron) and its dual, the [regular dodecahedron](https://en.wikipedia.org/wiki/Regular_dodecahedron). Each of the 20 triangles of the icosahedron are made of 3 puzzle tiles, and each of the 12 pentagons of the dodecahedron are made of 5 puzzle tiles. **Instructions for Assembly** Always push the "noses" from outside into the corresponding holes, even if there are multiple "noses" and holes in place already (twist tile correspondingly). For the final tile, you might need to broaden the shape at the inner surface of its hole at the long edge, using a knife, as here you'll need to push the hole onto the corresponding nose.
