Oh my god ! And I have just bought the mini master pentultimate of Greg

I know it'll be boring to say that but, Mass production please!!!

WOW!!! Correct me if I'm wrong but this is the first void puzzle where turning a face also moves the neighboring void centers... isn't it? GREAT JOB either way. It looks beautiful. Now I want to stick a void Megaminx inside. Which brings up a side question... has anyone yet made a void Megaminx which copies the mech of the Void Cube? I've never liked the current Void Megaminx as the holes don't rotate with the faces.

Similar... but not totally void. I still see some of the face centers remaining in the surface. And yes, I do realize removing that would be impossible.

P.S. Just remembered the Void Starball. It too moves neighboring void centers.

Amazing puzzle!

If this goes to massproduction, will we see it before a regular Master Pentultimate?

Not really, I think the void starball by Cubedude76 also has void floating centers.

Edit: Just saw your edit about the void starball.

Are these puzzles void because it is easier for you to make void versions than normal ones, or did you just want a bigger challenge?
I would totally cap these pentultimates before doing anything else with them. Am I not such a philistine.

(The last word I looked up in an online dictionary, so excuse it if it's not used.)

Void mechanisms of this sort are usually very sensitive to alignment and can't cut corners at all. I think this would be quite frustrating on the long solves these puzzles require.

In light of which I'm fairly curious as to why they chose to make a void version. Is it just that void is all the rage at present?

If I had to guess, I'd say that a shells mechanism build-up either has too many moving parts and doesn't turn well, or is too expensive to create all of the molds for and assemble. The Starminx didn't turn so well and perhaps adding another 20 pieces to it to make the Master Pentultimate wasn't working well at all?

Also, a Pentultimate has a very intricate core that fuses a center with a bunch of other pieces. This core is probably hard to create with injection molding.

I missed something... why are we talking molds and injection molding? The one pictured here is 3D printed, stated in the first line of the thread. Do we know this is planned for mass production?

I don't think we know if it is planned for mass production but my assumption is that it's a test of the concept and mechanism.

MF8, that is an interesting-looking puzzle and seems like a very sophisticated design. I hope we get a chance to see it stickered and turning. :mrgreen:

I understand that the Master Pentultimate is a challenging puzzle, so how does the Void Master Pentultimate compare? Twice as hard? Ten times?

I think it would be interesting if a major mass-producer such as MF8 started offering 3D printed puzzles, either through Shapeways or through their own facilities. I think it would make available some puzzles that were already designed but could not be economically mass-produced. Or perhaps they could offer the 3D prints in advance of mass production.

Now I'm trying to think of other MF8 puzzles that can be made into Void variants...

Since the centers can be arranged in any way you want and don't affect the rest of the pieces, a void master pentultimate like the one you see here is just about the center solving part easier than the normal one.
Also since you can't really use the centers as guidance concerning where pieces must go like on a 3x3x3 cube, it's not even practically more difficult.

Now if you could somehow stick a megaminx in there you'd get a damn cool Multidodecaheron without the wire frames for the outer MP pieces. That'd be badass!

Vadim · **Posted:** Sun Dec 02, 2012 6:31 pm

This is great, but I'd love to see normal Pentultimate and Master Pentultimate mass-produced first.
I had a chance to see one at UK cube day.
It was awesome!

Is it just me thinking this, but has mf8 done the void design to avoid any "ownership" issues with the Pentultimate and Master Pentultimate?
