Apparently Impossilbe Sphere- Large

A larger spherical version of the cube puzzle. Goes together the same way and is actually interchangeable with the cube parts. The sphere surrounds the original cube. See the picture. The bevels were removed from the edges to give a smooth looking sphere when assembled.

Since there are no flat surfaces to use as supports this is a little harder to align and put together when compared to the cube. Pinching the pieces together across the flat inside faces helps maintain an alignment so the pieces can be moved into place.

Print two of each of the pieces (they are mirror images) or print the 4 piece assembly directly.
