Professor Pyraminx

Timur · **Posted:** Sat Jun 05, 2010 8:55 am

Today I have finally finished the second version of Professor Pyraminx. Comparing to the first version, the mechanism was strongly changed to reach better stability. The tips can rotate now (many people asked about this).

You added twistable tips to this version. Good job, Iwas waiting for your v2 to come out ever since I saw your v1 and the tips were not twistable.

Very nice job! I love it. It looks very elegant and probably pretty tough to solve :wink:

OK, the answer is Yes. What is the question?

EDIT1: Sorry, that I had missed the question in the original post. :oops:

My answer is YES, too!

EDIT2: I was about writing EDIT1, when Aleksey had reacted already.

Awesome puzzle! What did you use for a mechanism? How durable is this one? I'd love to buy one from you very soon.

I hope I have enough money to buy this

It has a 4-armed spider with the corners holding all other pieces.
It's an SLS-full print in WFS material (Nylon), should be very durable.

I'm pleased you included the turning tips. Trivial or not, they qualify it as a Pyraminx-type puzzle and they make the visual pattern look good.

When I get around to it I'll try to build one without the pillowed shape!

Nice idea! I assume you will be trying to use the SD300's ability to make super thin (single layer) walls?

...uh oh. I think I inadvertently volunteered for a suicide mission!

To get back on topic, though, I did some of the geometry a while back and noticed that pillowing actually seems to make it harder to keep the middle-edge pieces attached. In other words, there's a limit to how deeply you can extend the pillow-shape before the middle-edge pieces will fall off.

@Timur: did you observe such a problem while developing this puzzle? Or did I make a mistake?

If the puzzle were not pillowed, the middle edge pieces would have nothing to hold on. Pillowing reserves some space for their "stem". I don't think there's a limit to make it more pillowed.

Ah! Thanks to your pictures I can see what I did wrong.

I had doodled the trigonometry on paper during a boring meeting and reached the faulty conclusion because I didn't re-compute where the slices intersected as the overall shape changed. I used the same edge-to-slice distance as the flat-faced puzzle, which would make the slices shallower as the pillow extends outward.

Naturally you didn't do that, since the whole point of pillowing is to gain effective depth for the outer layers. That's the hazard of scribbing trig on paper: you can't really see what you're doing!

Any chance this will be on shapeways or someplace it can be ordered in the future? I'm in the middle of a move and don't have the extra cash I'd expect this to cost but I'd love to be able to get this down the road. Or is this a limited one time deal to the few that make the highest offers now?

The chances are very high considering it's already available:

When I get on this page, I see this: "You are not allowed to view this model."

What is the reason of that?

I hid it because it's not available for order anyway.
