This nice puzzle doesn't have rods with a square diameter but the pieces are made of rods with a rectangular diameter. The puzzle is made of twelve pieces which are sawn in a shape of a diamond. The pieces are arranged in such a way that within the puzzle a space is formed in the shape of a rhombic dodecahedron.

for this puzzle are pine wood bars used with a diameter of 4,35 cm by 1,8 cm. This is a  standard diameter for boards in a regular wood shop. Other diameters are however possible but you get the best results using boards with a proportion between height and depth of approximately 5 : 2.
