Some may remember my post in the "Rare Puzzle Thread". The MFTO had been number four!
I have decided to include my review here and have deleted the separate thread.
Tom has added a new chapter to my Master FTO story.
I have never built any puzzles, but I think Tom and Timur will agree that some credit goes to me that improved versions of Master FTO have be born. History - short version
Tom has designed his version of the Master FTO after a request from me. I had been the winner of the original Master FTO designed and cast by Timur, which was a "collectors item", not really suitable for solving. But because I enjoyed the prototype so much, I wanted a better turning version which was designed by Timur for printing at Shapeways. This new version worked much better than the original prototype, but when I got it a few weeks later as my birthday gift and I tried to scramble and solve it, I recognized a hidden problem. As I had been the only buyer of the Shapeways version, Timur has expressed that he would rather concentrate on new projects instead of trying further improvements. I want to emphasize that Timur has made it on my request and with the goal to do a favour to me.
Because I really wanted a stable Master FTO, I asked TomZ, if he could try some different design.
TomZ's design takes a new approach based on his Dino Skewb design, adding an extra shell to support the deeper cuts. It also turns very smoothly and has no issues with stability.
Not being a designer, I feel somehow as the motor behind the project that brought this puzzle into existence.
I want to thank both designers, Timur and TomZ for responding to my requests.History in more detail
Timur has posted originally here
. As you may remember, the original puzzle was a mixture of casted and printed pieces.
I have won the prototype on Ebay
I have posted to the rare puzzle thread this
I have written a PM to Timur asking, if he could make an improved fully 3D printed version.
He responded to my wish and I could buy it at Shapeways. He made a special, unique price for me – as the unique Prototype buyer.
It has turned out that I have been the one and only buyer of the printed version, too.
I made a first review and the puzzle got packed away as my birthday gift.
When I finally got it mid June, I realized a stability issue of the ball core.
As I had been the only buyer of the Shapeways version, Timur has expressed that he would rather concentrate on new projects instead of trying further improvements.
Therefore, I asked Tom via PM to give it a try.
The Master FTO is a project I considered but wrote off due to it being too hard.
Before I had read this, he added an EDIT
Ok well, I got it sorted out. I just need to add an extra layer to my existing Dino Skewb design and it will work just fine. I hope I can get it to be a reasonable price/size.
later I got this
It is looking good already. I just need to make a few adjustments and export it for printing.
And now I have received it on Thursday August 11th and I think this is the final happy end of a long (love
) story.ReviewStability and turning
Out of the box, it is just great. It is completely stable and turns very well. It is among the best Shapeways puzzles I have got. OK, an occasional catching of pieces happens, but that is to be expected for a puzzle with so many pieces. (Timur's Shapeways puzzle doesn't turn badly either, but an implosion of the ball core can happen at any time. That is the "hidden problem". I had three or four such implosions until I had solved it - unfortunately twice very close to the solved state. And with implosion I mean that you are confronted with assembling all
86 visible pieces and some more invisible. Not just a simple pop. This makes the huge difference. No danger at all with Tom's
A picture does not show much, but with my lousy notebook camera I cannot make a decent video.
BTW, the colour to the left is not white, but a light beige.
Here it is among its predecessors:
To the right is the original (father?), to the left the Shapeways brother from Timur, in the middle is Tom's.
Here it is with the companions it arived with on August 11th:
BTW, Timur's original and Tom's have trivial tips, while Timur's Shapeways model doesn't.Size
It has the exact size of Timur's Shapeways version. The overall size is identical to the normal mass-produced FTO. One sticker triangle, before rounding, has an edge length of 12 mm.Solving
I admit that I have tried to raise interest for Timur's Shapeways version, by discussing the difficulty in my review thread. I'm glad that nobody else has purchased it, because the hidden problem was not recognized yet. Many Gelatinbrain solvers have solved the virtual version and they have judged it as easier than the Starminx. I agree with that and would say that it has the right difficulty for somebody familiar with the ordinary FTO and looking for an additional challenge: Not too easy, not too hard either.
Coming from a FTO going to the MFTO is similar as coming from a 3x3x3 going to a 4x4x4.
Hidden spoiler below:
1. Reduce the big edges consisting out of two edges and the two triangles in between.
a. most of them intuitively
b. the rest with two pure 3-cycles, one [3,1] commutator for the edges and another [3,1] commutator for the triangles (correct the colour scheme of the centres, before finishing step 1b)
2.Solve the big edges as a Dino
3. Solve the corners as on the FTO (corners are solved as edges on a Pyraminx)
4. Solve the remainig triangles quite similar as the triangles of the FTO with a third [3,1] commutator
Let me put it this way: This time, I would be very
surprised if my MFTO stays again unique in the universe
