This is one of Douglas Engels early and nowadays almost unknown creations.
Back then the inventor didn't bother to give it a name.
It shares its colour scheme with Rashkey 3.
The cutting depth is equivalent to Rashkey but the symmetry (3-fold in this case) is different.

Images 1-2 shows the version from 1982. It exists also a version with colours: red, yellow, black.
Image 3 shows the version Mr. Engel recreated 2009 under the name Triplex.
The puzzle is identical to the Mandorla. Please refer to the separate entry.
