This puzzle deserves a better
As there has been a single
reply after my post in Timur's thread
, I have decided to try it again with a new thread.
I have edited it at a few places only. An important addition you'll find under EDIT at the very end of this post.
So, if you have read it in the other thread already, you may want to go to the end of this post directly.
I hope to reach some more readers, though
Actually I have missed Timur's thread until last week. Timur has wondered already, why I have not made any comments.
For the impatient reader: “A long story has come to a happy end! I can certainly recommend this puzzle.”
Here follows a review of the Master Face Turning Octahedron
Timur has posted originally here
. As you may remember, the original puzzle was a mixture of casted and printed pieces.
Here are a few quotes from this thread:
WOW!! Congratulations on finishing this Timur!!
Now that's amazingnessation
! Now if you don't mind I'm off to clean up my brain off the wall
I am most impressed at you! Job well done! ...
Fantastic puzzle. Amazing work, Shim!
Wow, that is just awesome. I've been hoping that this puzzle was physically possible. Great job!

Wow, amazing! Looks like it functions really well. Definitely looks better when it's all cleaned up and dyed. Nice work!
That turns amazingly well! Great work, as usual. ...-pi (Eitan)
This is great! Well done Shim. I hope we'll be seeing this on Shapeways in the future.
I could go on for a while
And now it is available at Shapeways at a fair price, in a better
quality, and nobody
wants it? (besides me, who has one already
I have won the prototype on Ebay
on November 24th, 2010.
I have posted to the rare puzzle thread this
on December 1st. Quotes from there:
Timur had written: “If a turn seems apparently hindered, never apply force. In case you do, you’re not likely to break anything, but chances are you’ll see the mechanism in all its beauty."
I had made that experience and even not
applying any force.“My verdict is: Timur has not exaggerated and my feeling of danger is quite justified.
I'm afraid I'll never be able to solve it, because I will see "the mechanism in all its beauty " too often.
Definitely, a printed version would be a partial solution, only. IMHO, some real enhancements of the mechanism are necessary to make it more stable.”
I have written a PM to Timur asking, if he could make an improved fully 3D printed version on December 5th. As he has said above, if the buyer (me) does not care about the aspect of uniqueness, nobody can blame him (the designer), that the (pretty high priced) Ebay puzzle is no longer unique. I liked the idea that I could influence Timur that he would make this puzzle available in an usable and playable form
I got PM from Timur on April 5th that I could buy it at Shapeways (I had missed this thread from March 29th). He made a special, unique price for me – as the unique Prototype buyer.
There was some delay at Shapeways and I have received the parts on April 21st. Unfortunately, Timur was on vacation at that time. I got some important hints for the assembly yesterday. And now I have another unique version of this puzzle
(Unique in the sense, that I have been the first one to order it on Shapeways. I hope, I'll be not the last one.) Let me state here, that I do not like so much if puzzles are available to a single person at a unique price. I'm more for the democratic approach supported by Shapeways for custom puzzles.
Until yesterday I lived with the impression that the improved version is still a secret Assembly
I have ordered the puzzle in BSF (Black Strong Flexible, which is White Strong Flexible dyed black).
Next time I'll try WSF and dye the parts with a black marker pen.
Actually, I needed a fundamental - yet simple - hint from Timur: Start with the ball core and adjust the screws until the turning feels right. The outer parts can be installed afterwards.
I had made the mistake to make the screws completely tight and that caused problems.
So, make the screws a bit loose at the beginning and assemble the 14 pieces plus the four-armed spider, making the ball core with the six corners extruding. (BTW; no washers and springs needed, just 4 M3 screws 10-13 mm long):
- The four triangles in the picture above
- The six corners
- The four triangles
Actually, with these simple hints things are quite obvious.
The rest is not very complicated as well:
- The 8 centres go with two types of adjacent outer centres, four faces with larger triangles
- and four faces with smaller triangles
This makes two types of faces which are opposite to each other.
Build large edges that consist of two edge pieces and two of those outer centre triangles of different type and you will find out easily how things fit together.
Don't be afraid, with these hints the assembly should be pretty straight forward.
One more hint: Some pieces (the little triangles) have tiny holes where superfluous powder could have remained.
Knock them on a table to get rid of this powderTurning
The puzzles feels a bit loose, but pretty stable. No dangerous feeling at all. It turned quite smoothly right after the assembly.
It is a great relief that it turns so much better
than the prototype.
Honestly, I have not solved that one and I'm not one who is complaining easily about badly turning puzzles
Still, you have to align it and it is not for speedsolving. But you will not have expected that from such a complex custom puzzle, right?
All in all, I'm quite pleased
how it turns.
It will certainly improve over time as all my Shapeway puzzles. A few more sessions of lubrication (if you are familiar with WSF, you know what I'm speaking about) and some more breaking in and it will be excellent.
Please, look at the EDIT below for an important addition!Stickers
I have sent a Coreldraw template to Olivér (Nagy) of this forum and he has produced nice stickers for the puzzle. I followed Timur's advice and made the stickers with an edge length of 12mm before rounding the corners.
I'm quite pleased with the result. Here are some views of the stickered puzzle:
Olivér has lots of colours to choose from.
He offers a set for € 4 plus shipping.
I have used Greg's ironing method in two steps:
- Ironing the surface of the unstickered puzzle right after assembly.
- Ironing on top of the stickers with less heat and just for a few seconds.
It has worked quite nicely (A funny observation: One colour - purple - did not adhere well. I had two sets and both
didn't work. I have replaced the purple you can see on the picture by dark blue and everything is fine.Size
It is a bit smaller than the (unique = I'm the only one who can make that comparison
) prototype and has the same size as an FTO from Taiwan:Solving
I had developed the necessary algos on Gelatinbrain 4.1.5 back in December.
Actually, I managed only one single commutator once on the physical puzzle and gave up.
That was the point in time where I have asked Timur, if he could make a better version.
I have never solved a scrambled 4.1.5 (I have never tried any
scrambled puzzles on Gelatinbrain) and I'll have to wait for another six weeks, because this master piece will be my birthday gift
My impression is, that it is in the same category (how hard it is to solve), as the Pentultimate or Starminx V1 (the real V1).
Maybe the Gelatinbrain experts can compare it better?Conclusion
I would be surprised if this will ever be mass-produced. At $ 250 it is a very good Shapeways puzzle.
If you can afford it, I wouldn't mind if you go and set and end to the state of "uniqueness" of my puzzle.
Whoever wanted to beat me on Ebay should order it immediately and get a much better puzzle for much less money EDIT
: After I had made my first reply in Timur's thread and before it got packed away as my birthday gift, I tried some algorithms. As always with custom puzzles, the puzzle was a bit harder to turn and to align when doing real life sequences compared with random breaking in moves. I have had two pops and larger parts of the puzzle came apart. So, either you handle this puzzle with care - as I do it now after my "accidents" - or you will be very well trained reassembling it, after a while.
The good news: It is completely
unlikely that you will break any pieces.
