Hi All,
Below you will see my modification of a pyracosaminx to put the tips on to form an icosahedron. It took longer than I originally thought it would because I improved the internals so that pieces can not be popped inside the puzzle (which tended to happen due to the oblique angle if one was not careful aligning a side). I also added ball bearing locators on the tips, which were trickier than I thought, at that size.

Anyway, I am calling it Tutt's icosaminx since icosaminx is already taken and it really looks like a pyraminx triangle side but as an icosahedron. This also completes the set of 3,4, and 5 triangles meeting with the pyraminx triangles at a vertex (see picture of pyraminx, magic octahedron, and Tutt's icosaminx).
The size is the same as a dogic with 180 stickers in 20 colors. It turns pretty well. so I am happy. :D
Lee

Thanks. I have not done a complete scramble but it is identical in difficulty and solution to the pyracosaminx. The tips are more cosmetic than puzzle significant, like in the pyraminx.

What mechanism did you use? This sort of reminds me of the 2 puzzles below because this one has higher order triangles to. I do remember that Tony Fisher said(I think but don't quote me) that he wanted to make this a while back or something like this.

Aleh's Master Octahedron.

viewtopic.php?p=24377&highlight=#24377

and

Katsuhiko's Master Pyraminx

http://puzzle3d.hp.infoseek.co.jp/mpyraminx.html

What colors are there and does it have 20 of them?

:oops: All that I know is that I'd love to have one!!!!! :oops: Sorry!!!!

This deserves the right to go in the database!!!!! :wink:

Beautiful. I think it looks better than before, and I still loved it then. I just find icosahedrons to be a beautiful shape. I love how it's the same size as a dogic.

This has definately joined the ranks with Aleh's Brillic and Tony Fisher's Golden Cube of my favorite puzzle designs.

I am particularly thrilled to see this puzzle.

Some time ago I noticed the geometry of Ryan Thompson's Pyracosiminx looked like it was planned to be built up into an icosahedron. I grabbed an image from one of his videos and Photoshopped it into an icosahedron, and he assured me you both had already thought of it. He didn't say you were actually working on it, and I didn't pry.

I have a theory that this icosahedron is capable of all the patterns a Pyraminx can do, and most of the patterns a Magic Octahedron can do. (It wouldn't be able to do certain octahedron patterns that have odd faces and even faces.)

Just for fun, I've attached my Photoshopped image. The quality is only mediocre, but I think I got pretty close considering I was only guessing!

I second that. The many identical, regular triangles on the sides must've required exceptionally precise work.

(Oh please interpret that Photoshopped picture as a tangible sign of interested enthusiasm, not an attempt to steal your thunder.)

You deserve extra credit for installing all those trivially-turning tip pieces. They really do complete the aesthetics of the puzzle, but there just are so many of them it must've gotten pretty tedious!

What can I say that hasn't already been said.
It's incredible and it looks absolutely perfect.

I want one!

Lee, this is beautiful work. Can I ask how you did the ball bearing stops?

The chinese megaminx core. Also, there are 20 colors, and this is not a master puzzle as in the one you showed. That would be an awesome puzzle. note there are only 3 subtriangle on an edge not four.

VeryWetPaint: As you surmised I designed Ryan's pyracosaminx with this mod in mind originally for later. I had only mentioned I was working on it to a couple of people.Your pic is great showing the mod! No, I did not take the picture as anything but in enthusiasm. Thanks. The regular triangles were not much problem as they are easy to generate using solid modelling

Vadim: Thanks. The puzzle took longer than I anticipated. I was working on it for ~ 4 months after I finished the pyracosaminx as the mods I had to try a couple of ways before I was happy.

io : the ball bearings are .1 in teflon balls on a .088 OD spring in an offset hole on the cap. A cylinder, just a hair larger than the pentagon hole, has 5 radial V-cuts acts as detente spots and that is just screwed into the cap through a center hole with a washer. The cylinder is then just pressed into the hole. I think in the future I may go to a slightly bigger ball as this does not quite give the amount of stop as I would like.

Thanks all
Lee

Congratulations Lee.
The puzzle really looks amazing.
In fact I can only repeat the comments that were made already.

Apart from the beautiful design and the great craftmanswork in making it, I also very much like the fact that it more or less completes a small series of puzzles.

Regarding the tetrahedron we all know the Pyraminx with its equilateral triangles but there is also the tetrahedron design made from a skewb (probably initially made by Tony Fisher and lateron also by others). Regarding octahedra, we respectively know the Magic Octahedron as well as Trajber’s Octahedron. Regarding the icosahedron until now we ‘only’ had the design made by Jürgen Brandt (and lateron also e.g. by Carter Tarrer).
Tutt’s Icosaminx completes this series with a design having equilateral triangles.
Fantastic work!!!

Wow, I definitely missed this thread while I was on vacation a few weeks ago. (Thanks for bumping it Tony)

Awesome puzzle. Like everyone else said, it really awesome to see a puzzle that seems to "complete" the tetra - octa - icosahedron sequence of puzzles.
