LIZARD JIGSAW SHELVES
At the turning of research on plan tessellations, the idea came to me to develop a set of interlocking object.
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 and three studs.
