The inventor is Mr. Tang. “Penta Gem uses a hybrid axis system of face and corner turning dodecahedron, it has 3 face-turning axes with the same cut depth of Pyraminx Crystal and 1 corner-turning axis with the same cut depth of Chopasaurus Jr.I got the inspiration of this puzzle from Basic Gem and Junior Gem, The geometries of these two puzzles share similar characteristics: one is composed of square faces and pentagonal faces, while the other has regular hexagonal faces and pentagonal faces. So what is the geometric shape "between" them? I think it's a dodecahedron. So I adopted a similar design concept as these two puzzles, making a similar cutting pattern on the dodecahedron. Therefore, this puzzle can be regarded as in between of Basic Gem and Junior Gem. “———— TP ref: https://twistypuzzles.com/forum/viewtopic.php?t=40427This cube has been printed by two kinds of method & material: 1.
