Excerpt from AP-ART by Stewart Coffin
This is a distorted variation of a 12
piece construction that is in turn a variation of
Twelve-Piece Separation. The distortion is by
compression along one of the four-fold axes of
symmetry. I include it here, not as a practical puzzle
design (it is woefully difficult to make and assemble)
but as a specimen of whimsical woodcraft. One
redeeming feature for the intrepid woodworker who
may wish to give a try is that all sticks have the same
50-65-65-degree cross-section.
The pieces are made of triangular sticks with
triangular stick segments attached at both ends,
except for the three mutually parallel key pieces that
are plain on one end, [marked K] in the photo, with
their missing segments, outlined and [marked A],
attached to adjacent pieces.
