Chebyshev linkage wheel variation -A. cf. N=3 variation -B This is the my official version of Chebyshev-like N=3 Polygon Wheel (original concept version). Antiparallelogram application. ----  My last concluded/ sophisticated official version. ---- I think that this apparatus is useful in real world. --- but, As a fact, N=2 is enough/ sufficient.
Hexagon CD''D'1DD'F is rigid body. Lozenge HH'EH'1 is rigid body. Memo: Rabatment/ line-symmetry = 180° -60 = 120°, +60 = 240° (=360-120) ■ 3D implementation above implementation is more/ far complicated than N=2 case. --- So, I recommend N=2. (I prefer N=3, but it's somewhat difficult. i.e. This world is bothered. If I were a worm on the ground. N=2 or N=3 is indifferent thing. It looks the same. So, N=3 is not needed. If inner structure were hidden by the cover, N=2 or N=3 is hidden. so, N=3 is no meaning. ) ■ my Know-how/ how to easy to make/ avoidance of conflict : To separate the 3D layer (Blue | Black [= middle] | Green) clearly, +60 rotation should be implementation from X-bar one side (& mapping it to corresponding bar), -60 rotation should be implementation from X-bar another one side (& mapping it to corresponding bar).
