A polylink constructed from four non-planar hexagons,
where each hexagon links with the three others.
Uses beams with a square-root-2 rhombus as cross section,
such that the cut faces are squares.
The connections between beam segments are regular miter joints at 90 degrees,
and skew miter joints at 120 degrees.
The original is in wood.
