Martel

To commemorate Edouard Alfred Martel, the first speleologist (speleology is the study of caves), Mr. Latussek has named his new puzzle after him.
You have to “make holes out of holes”.
12 equal pieces of wood with a central hole must be put together so that no hole is visible from any side.
A very tricky packing problem with a surprising solution.
