新品种魔方－十二轴二阶六面体魔方（英：Helicopter Cube ）

大烟头

  这是最近出现的一种新式魔方，英文名为“Helicopter Cube ”，直译为“直升机魔方”。我分析其旋转特点，这魔方有十二个旋转纹路，判断出这魔方为十二轴的，两旋转层相交有两个共有的块，所以这魔方应该为“十二轴二阶六面体魔方”。

Here is my latest puzzle...

The Helicopter Cube

A few vital statistics:
It turns about an edge axis (180°) and has 12 axes of rotation.
It is the same size as a Rubik's cube, but weighs approximately twice as much due to the solid resin parts.
All parts of this puzzle are custom made.
The central spider used in this puzzle was 3D printed (yes it is strong enough)

The movement of this puzzle is very good, and there is no problem with the puzzle coming apart. In fact due to the way the prts interlock, I can remove one of the axis screws and the puzzle will not fall apart.
The puzzle itself is challenging, but not overly difficult, but as has been discussed many times in this Forum, difficulty is very subjective term.

This puzzle is one I have been thinking about for a long time (several months before I found this Forum) and now that I have found a method that works for me, I am able to make my ideas real. There will be many more to come.

Enough chit-chat, on with the pictures!

看来就是被我用做头像的这款魔方了！为了速拧helicopter cube，在原有教程的基础上我有总结了一些新的中心块循环公式，总共有19个公式，难度还可以。

日本人岡本勝彦那种的称为Bevel Cube，其结构我就看不懂了。看来是混合轴的。[em06]

说来也很巧，日本的岡本　勝彦（愛媛県松山市在住　44歳，製造業を自営する職人です）差不多在同一时期内也制作出这魔方：

岡本　勝彦：Hello Adam,

I was very surprised to read this article.

I had already completed the same puzzles as your puzzle last month.
And I had sold them to few puzzle friends in Japan.

I had not disclosed information for certain reasons.
However, I updated my site and opened my Bevel Cube to the public ahead.
I named this puzzle "Bevel Cube".

However, my Bevel Cube may not be the same as your Helicopter Cube.
It is because my Bevel Cube can be transformed.
