An axis cube from a Master Skewb has already been made but no Hexagonal dipyramid. Strange.

Hello, it isn't strange, one of the biggest problems is that But I think it isn't insurmountable.

Not surprising indeed. I made the axis master skewb without actually cutting it into HD first, since that seems too deep of a cut, so I made much shallower cuts and extended it into cubic form. If I was to make a HD, I'd do the same shallow cutting and extend it.

Hello, is a great way to do it, my compliments, but from my point of view, extending the puzzle would not be a pure HD shape derived from Master skewb but rather an extended HD Master skewb;

thank you very much for having participated and showed your way.

Best regards
