Click a thumbnail to see its larger version and description.
A 3x3x3 truncated on 7 edges and afterwards extended. The result has a shape hard to describe.

This puzzle is part of the series "Octgonal Edges". All modifications of this series are made by truncating an 3x3x3 on its edges. These truncations are symmetric as in the mass produced octagon from which the series takes its name.
The technical signature (Octagonal Edges Extended 21E8800144087) indicates where to cut the original cube.
Without the keyword "Extended" it is a variant made only by truncating the original cube. With the word "Extended" some sides left over from the original receive additional extensions to "delete" some of these remaining faces.
Edge length: 40 mm (top)
Edge length: 68 mm (short trapezoidal edge)
Edge length: 100 mm (long trapezoidal edge)
Base length: 36 mm (short)
Base length: 75 mm (long)
Weight: 182 grams

The non-extended variant is shown in image 4.
