A truncated and extended 3x3x3. Similar but not equal to Greenhills Cube.
This modification of a 3x3x3 is closely related to the cushion cube and to Greenhills Cube.
It looks very similar to Greenhills Cube but the latter has a true hexahedral shape and is slightly different orientated inside the solid while this one is rhombic prism.
To build this variation, the builder can start with the cushion cube which is a 3x3x3 with four truncated corners. These faces will be the rectangles of the final puzzle. Afterwards the two unmodificed edges are truncated like the octagon. These faces will be the rhombic faces of the final puzzle. After this two steps of truncation the remaining faces are "deleted" by apllying extension to them.
The first but unstickered sample of this puzzle was presented by Kevin Nguyen. The second (stickered) sample was presented by Rex Rossano Perez.
The first two images presented here are made from the sample built by Andreas Nortmann. Its stickers show some non-functional gaps.
Edge length: 57 mm
Height: 55 mm
Weight: 198 grams
