: Locate the small hole at one end of the model. Blow into it steadily until the paper expands into a cube. Method 2: Modular Sonobe Cube
Continue connecting the pieces at right angles. Each face of the cube will eventually be the center square of one module, while its flaps lock into the adjacent modules.
: On the top layer, fold the two bottom corners up to the top peak of the triangle. Flip the paper and repeat on the other side to form a diamond shape.
The final piece will tuck into the remaining open pockets to complete the 3D structure. How to Fold Origami Paper Cubes
Tuck the corners under the existing flaps to secure the module into a parallelogram shape.
: Take the small loose flaps at the top and tuck them into the little pockets you just created in the previous step. Repeat on all four sides.
: Flip the paper over and fold it in half horizontally, then unfold it.
: You need 6 square sheets of paper, all the same size. Fold the Modules :
