Ladies and gentlemen, I'd like to present you with the first higher order pentultimate :)

I am quite pleased with this puzzle, it turns beautifully. Many thanks to Drew for letting me butcher his beautiful Starminx designs to create this! Stickers are on the way, I will post more pictures when I have them. I am currently building two more of these. The one pictured here is for eBay, the next two are for Geert and Drew.

And for some reason, I cannot attach my photos to this thread, so please click the links below.

WHAT?
When I read the title I was confused thinking about what a pentultimate was again because I knew I was wrong thinking that it is what it actually is. But you seriously built a Master Pentultimate, and on top of that it isn't even bigger than a pyraminx crystal?!!
This is so... I can't believe this.
Is this in the top 3 of the best puzzles of all times in my opinion? I can't really tell but probably.
Wow.
But what did you mean by "butchering Drew's Starminx Design". I mean did you really butcher a built Starminx? Or did you just mean to say that you in some way "copied" the design of the mechanism to create this?
I am so in awe.

Wow, crazy! I dunno if I'd call this the master Pentultimate, though - to me it is the 3x3 version :)

Would you mind telling us how it works? I'm very curious.

Wow that is absolutely crazy. The pentultimate seemed to be impossible to build, and now even this exists!

And to think, deep, deep down, there's a megaminx in there :P

Alright some of the shock has worn off. After seeing this i went over to gelatinbrain and gave it another solve and even though i agree that master pentultimate is a great name for it i wouldn't really call it a higher order pentultimate because that would almost be like calling a starminx a higher order pyraminx crystal. It is much more like a cross between a sterminx and a pentultimate as it contains all the pieces from both of those puzzles.
That aside GREAT build (although it looks like a full print so is build still the correct word?)

Very cool!

Seems like this mech. could be used to make a regular Pentultimate too. Just put hats on the corners and centers that cover the new layer, similar to how the V6 is really a V7 with a hidden layer. Of course it would have to be clicky to prevent internal lockups...

Congrats scott! great job! though the faces need some sand paper love!

I suggest placing parts on a flat hard surface,200 grit them until they are smooth and grey

How well does it turn?

Jason's Pentultimate uses a different design, by the way, which doesn't have so many internal layers.

Woohoo, awesome! :D

Does the turning quality match the quality of Drew's Starminx, or is it a little worse?

this is very awesome.
does it have a similar core to the pentultimate?
i have to agree that cube technology is progressing extreme fast!

This is a great puzzle from a great builder.

Boublez, Scott can correct me if I am wrong, but this puzzle uses the exact same core as the pentultimate, but the cuts are slightly more shallow therefore revealing hidden pieces.

The mechanism is the exact same as the starminx, just built up another half layer

Actually there would be no need for it to be clicky because it is a dodecahedron.

The shape has nothing to do with it. The mech has everything to do with it.
You can do something similar to the internal structure of an Eastsheen 2x2 and glue some of the pieces together to make a single static corner.
If you search for the thread called "Pentultimate Writings" you'll find information on exactly that.

Scott,
Congratulations, I knew that you were working on this for some time and the fact that you succeeded in completing it and making a working sample is truly fantastic.
This is indeed one of the best puzzles that was ever designed and built,

Geert

Nice!!!! We are now one step closer to having a full Face-Turn Multidodecahecron. This is one of the two puzzles needed as seen here:

http://twistypuzzles.com/forum/viewtopic.php?p=179431#p179431

I wonder how long it will be before we see the Hybrid Megaminx-Pyraminx Crystal. Then we'd just need a way to tie the two puzzles together. Maybe make one puzzle radio controlled and the other puzzle the controller.

To be honest I sort of expected to see the Hybrid Megaminx-Pyraminx Crystal first. I think custom puzzle making methods are advancing so fast we are now jumping over some of the easier puzzles in the rush to see who can make some of the more complex ones first. It's amazing times we are living in.

Seems like a good time to admit my Pentultimate version 2 is a Master Pentultimate with caps covering the master pieces. :)

That's what I figured. But somehow I don't think your "Master Pentultimate" has any special underlying mechanism like a Starminx. Why? Because I have a mechanism in mind. 8-)

Very nice work. Can't wait to see the finished product. I love hearing when two puzzle builders/designers ideas come together to create a great puzzle.

This puzzle seems to be related to Pentultimate in the same way that Master Skewb is related to Skewb. Master Skewb is intermediate between the Dino Cube and Skewb; Master Pentultimate is intermediate between Starminx and Pentultimate.

Yes, but you are referring to an extremely overcomplicated Skewb that results from an octahedron internal geometry rather than the tetrahedron that can be easily made.

The master skewb is a little weird in that it's most naturally built by making a skewb and then adding the master pieces in the outermost layer. The skewb has a special property that four of the corners can be directly fixed to the center, giving each slice orientation in a way where everything holds in nicely. That trick doesn't work for any other deep cut puzzle. For the rest it's most natural to build the master puzzle and then cover it like in the 2x2x2. The deep issue with the pentultimate is getting the buried central slices to not spin freely and jam up the whole puzzle. It can be done via the shells method using careful gluing, although that requires a buildup of megaminx -> pyraminx crystal -> starminx -> pentultimate. Jason came up with a trick which involves a lot fewer pieces than the shelled method, and his pentultimate v2 uses that, although it does have the master pieces under the very outermost layer, which makes it so that even though it has fewer layers the number of pieces it skips out on isn't as much as you might expect.
