The original is made from a wooden beam, consisting of 12 segments
with as cross section a parallelogram,
such that the cut faces are rectangles.
The joint angles are 60-degree regular miter joints and 120-degree
skew miter joints (rectangular mitering).
In this miniature replica, the beam has a rhombic cross section,
such that the cut faces are rectangles.
