Design by Arie Brederode

The Rhombic Knot is a variation on the Wooden Knot Puzzle. The six pieces form two pairs of three pieces which can be shoved into each other. A solid figure will be constructed in the shape of a rhombic dodecahedron.   

The puzzle is made out of six pieces. These pieces are all identical. In the picture above all the six pieces are made out of a different kind of wood, but of course, it is possible to make all the six pieces out of the same kind of wood.

The graph below shows the pieces. The pieces have a two fold symmetry. The pieces can be made out of a wooden stick with a square diameter. You can also construct the pieces out of three different parts. If you use a square stick, use one with a diameter of approximately 1.5 inch.

 

If the design graph above is not clear enough, than you can use the paper model. This model is also very useful in making a draft puzzle and to found out how the principle works.

Beside this, the Rhombic knot is a very suitable to make a lot of different puzzle variations...
