Well after the Void Pentagonal Prism I decided I wanted to see how far this could go. I think this is it, well with proportional things and being strong enough to work. The pentagonal prism was the first void prism I have tried and I learned a lot from it, I believe the video will show that well enough.

I also increased the thickness of the rails in this one, didn't break any "centers" and the puzzle has no flaws. This is the best puzzle I have ever built.

I am offering it up for sale for $280 USD plus shipping (about 20 for priority mail or registered mail, about 40 for express) PM me for offers.

I may or may not make one more of these in black, don't really have any intentions of putting it on shapeways.

More pictures can be seen here.

p.s. this is my last adaptation of the void mechanism, nothing more planned.

Admit it, you just want to save up material

Good job, it looks really nice =)

Typically I have never been a huge fan of void puzzles. However, the pure beauty of this puzzle has completely changed my mind. Congratulations, it looks wonderful!

What keeps the corners held in? It seems like they'd just fall out but the video proves otherwise.
Very nice puzzle. How far do you think you could take this?

The corners work exactly as they do in the void cube.

Thanks for the comments

The edge length is 57mm. So far so clear.
What about its weight?

The puzzle looks to be very "empty". This just begs the question: why not make a "void" twisty puzzle ring or even bracelet? Through a system similar to a moving circles puzzle like Eitan's Pascal's Jumble, you could have a ring that has moving circles on the exterior surfaces (although applying them to a true curve would be difficult). To make it easier, you could apply the geometry of a Pentacontakaipentagon, or something like that which closely resembles a circle. The only challenge would be having some very small parts.

In short, I guess what I am saying is that this looks very "empty", like a ring or bracelet. The application of the mechanism to a rectangular shape on the side faces is very neat, and I will have to take a closer look to see exactly how it works.

Cool puzzle Matthew, although I do agree with Quicksolver that it does appear a bit 'empty'. Nevertheless, an brilliant puzzle.

What is the in-radius of the main void? In other words, what is the largest sized wrist that could wear this a shackle style bracelet?

Unfortunately I still don't have a scale, maybe next time I go into town I will pick one up.

It does look very empty, but I like that fact, I think it makes it look even more impossible.

This picture should answer questions about dimensions. They can all be calculated, but solidworks does it nice fast and easy.

And having big hands gets in the way again(My hand is about 9 cm wide across the knuckles). Still, it is one of the most "impossible" looking of the Void Puzzles. Imagine people's looks of disbelief if you were to wear a pair of these on your wrists and then scrambled and solved them while wearing them.

I don't think you'd have to get it over your hands. Just assemble the puzzle already on your wrist. Probably couldn't do that with one hand so I suspect you'd need help.

That might be doable, though having to assemble/disassemble every time I wanted to put in on/take it off would be annoying.

Really nice concept!
I like the size of the sides (you can use standard cube stickers for it)
Next one: Void Octagonal Prism?


If you want to make a bracelet from it, it should be a little bit larger, and it would look better in the shape of a cylinder.

Extremely nice puzzle!

This is really a great looking puzzle.
