A 3x3x3 half-regularly truncated on 3 corners. The result has a symmetry never seen before in a shape variant.
This puzzle is part of the series "Sharp Corners". All modifications of this series are made by truncating an 3x3x3 on its corners. These truncations are not regular as in the Half Truncated Cube. One dimension of the cut goes deeper than the other two. This half-regular style of truncating a corner was popularized by the Hexagonal Dipyramid. The cutting depths do have to go as deep as in the Hexagonal Dipyramid. The Triakis Tetrahedron is another example which uses half-regularly truncated corners too but with diffrent cutting depths.
The technical signature (40000040010) indicates where to cut the original cube.
Some members of this series are made solely by truncating. Others receive additional extensions to "delete" some of the remaining faces.
In this case three corners are truncated like this. The result is a shape with a 3-fold symmetry. The shape can be rotated around a corners without changing the view if stickers are ignored.
An extended variant of this was built parallel.
