At the turning of research on plan tessellations, the idea came to me to develop a set of interlocking object. Here is a first design for the house.

The lizard pattern inspired by M.C. Escher is a good start. Here is a shelf (190x180x30 mm) that can fit into its neighbors. Just print several.

For reasons of shelf size this model is in two parts, plus three studs. I advise you to play on increasing the scale rather than on the reduction. Because of the thickness of the walls.
