NOTE that this model has the cage and nugget both printed in plastic. Please order a metal nugget
here.
Nugget is a take-apart puzzle. The object is to remove the gold nugget from its cage. However, the nugget fits only through one of the holes and in only one orientation.
Nugget is based on a rhomic isocahedron, which has 120 isometric orientations. The frame has 6 holes. And out of those 720 combinations, there is only one where the nugget fits through the hole.
