Design by Stewart Coffin

This puzzle is made out of eightteen six-sided-center-blocks . Making this puzzle is therefore not very difficult, but you have to saw the pieces very accurate. The puzzle is formed by six identical pieces. These pieces can be put together in the same way as the wooden knot puzzle.

You saw eighteen C-pieces out of a stick to make this puzzle. The description of these C-pieces are found on the page of the rhombic blocks. Three C-pieces form one puzzle piece. The parts are glued together as shown in the diagram below.
