1 Information

The assembly method for the Sonobè cube can be generalized to make any type of polycube, such as extruded “Tetris” tetrominoes or the Soma cube.

2 Folding Modules

The modules are described on the Basic Sonobè instruction page.

3 Assembly

Each module creates one unit-square-sized face of the ﬁnal model. The two end points of each module can be creased up or down or left unfolded, depending on the direction of the edges ext to that face.

Figure 6:

Part of the model may have to be “exploded” to install new modules.
