The Slit and Assemble Cube and the Slit and Assemble Sphere
 
This page is being used to collect information about the history of the designs I call The Slit and Assemble Cube and The Slit and Assemble Sphere, both of which are made in three pieces arranged along the x,y and z axes of the design, the only difference between them being the external shape of the pieces..

There is another very similar design, The Puff Ball, which is made in four pieces, which do not correspond to the x, y and z axes, which has a page of its own.

Please contact me if you know any of this information is incorrect or if you have any other information that should be added. Thank you.

At first sight these designs might not appear to be paperfolding designs. However, they cannot be assembled without folding the pieces from which they are assembled and thus, to this extent at least, qualify as paperfolding designs.
