Four hexagons

[rolly_wood]

I take inspiration from Twist by Theo Geerinck. It has the same shape and the same method of joining intersecting hexagons: half-thickness-joints. However the method of construction of my version is much simpler and the assembling way too, since it uses magnets.
I do not know if, in this case, my puzzle worth a different name or should I call it modified version of Twist... Suggestions are welcome

Anyway the puzzle is here: http://forum.eagleswoodworking.com/index.php/topic,162.msg1676.html#msg1676

An animation on how it is assembled is here http://www.youtube.com/watch?v=o7IEOiCNCqE

48 isosceles trapezia have to be prepared and glued in pairs like this: (figures in millimeters)


Drill at the center of the rhombic surface at both sides.

Of the 24 pieces, cut half-heigth notches above on 12, below on the other 12. Surely you have router, dado blade or other suitable tool, I used chop saw with the angle set to 19.5 degrees.


Then glue 48 small cylindrical magnets in the holes with this polarity. I used 2 components epoxy

 
Last: Make stop crying the child to whom you have stolen the magnetrix toy for extracting the magnets 
I really did it but I had his approval before. ..of course there are many places for buying them (e.g. http://www.supermagnete.de/eng/index.php in europe... )

Chinny: I am not a teacher, I am waiting for the instructions of dimple-version of your soccer ball, so the student will be myself. I willl post also Hyperball be patient 

Canuck: Thank you I did not know this site, just saw the twist puzzle on IPP. I see that the Tetragonal Sixlink looks the same of http://www.georgehart.com/puzzles/puzzle-6squares.html ....
         Polyhedra are a not a set of inifinite elements.... all in all

Utahfan: beautiful! it remembers Coffin Pieces-of-Eight although is different!

Should we use nicknames or real ones? I am rather confused  Or even nick-nick as Chinny or Rolly Poly?

Sorry Rolly, when I mentioned a name for Bernhard I was talking about a new name for his group of puzzlemakers in Europe   Please feel free to use nicknames or whatever strikes your fancy, nothing official here, just fun   As the saying goes 'you can call me anything, just don't call me late for dinner'
