This model is a structure composed of six linked squa-

res, and belongs to the set of Dr. Robert J. Lang’s

polypolyhedra (see http://www.langorigami.com/

science/polypolyhedra/polypolyhedra.php4 ). The

same structure has already been implemented in a mo-

del by Michael J. Naughton, with tubular frames. The

present version represents a diﬀerent origami solution,

using 120 ◦ modular units.

Its construction requires 24 sheets of rectangular paper, with dimensions in the relation 5:11

(3) Fold corners to centerline.

(4) Fold on existing creases. Execute the

indicated folds at the same time.

(5) Repeat step (4) on the right side.

(6) Fold in half.
