This is the 14th in my series of increasingly deeper cut face turning icosahedrons. This is the second to last puzzle in the complete series of 15. The next and final puzzle in the series is the Radio Chop (These names have recently been shuffled around as a nod to the Chopasaurus).

This is a very large puzzle. With the cuts at this depth, we must have a very thin slice ring around the puzzle, which creates some very small parts with acute angles. In order to make the puzzle work, it has to be large.

Check out the size comparison below with Radiolarian 3!

There are 362 external parts, giving this puzzle close to the number of external parts on a teraminx, with the smallest part on this puzzle actually about the same size is a small teraminx part.

It jumbles in the same two ways that previous Radiolarians jumble, but because of the depth of these cuts, the jumbling moves seem to take about 1/5 of the total pieces along. Jumbling images are below.

Turning is quite good considering the depth of the cut, especially once the parts are jiggled into alignment. It has more friction than I like. I'd love to see a polished version of this some day.

Video here.

:shock: :shock: :shock: That thing is absolutely incredible.
This series has so far been amazing, the amount of time, effort (and cash) that you've placed into this is beyond describable. One more puzzle and it will be complete. I can't wait to see all of them together.
I cannot complement you enough! You are one of the best designers on this planet...

Beautiful. That thin "master layer" matches so many other very deep puzzles like the Master Pentultimate.

I'd love to see a polished version some day too :lol: Those big parts would be a real challenge for the tumbler though. The tips and sharp edges would wear so much faster than the faces. Someday :)

Congrats Jason, another amazing puzzle. That thing turns amazingly smoothly considering the complexity of the mechanism. Since this is the second to last in the series, you should have called it the Pentultimate :lol: Could you give us an idea how much this cost to print?

This was around $500. Bigger does cost^3!

Also here is an update to the full list with the correct names.

Great to see the summary page and which ones worked.

I know that at least 1 is available on your shapeways store - of all those you have managed to get to work which do you think makes the best puzzle - in terms of movement and also of solving fun?

Having received 2 and waiting for another Shapeways puzzle, I might well see another (maybe a Radiolarian) in my future! :shock:

In practice it's usually more like aX^3 + bX^2 where a is small and b is close to 1. Since parts are shelled, if you maintain a constant thickness of walls then you can think of the scaling as 2-dimensional. In practice some features do get bigger in 3D and sometimes you make the walls thicker.

Even at $500 this is a very tempting buy. I do hope eventually it and the rest of the series goes up in your shop :-)

WOW!!!!!!!

This is amazing. SO CLOSE!!! :P

I wonder why the cuts on deep cut puzzles look so... 'nice' when compared to the shallower cut ones.

This is absurd. I can't wait to see the full family photo. Perhaps you could do a gif of all of them kind of like the animations that Carl used to make.

The size comparison is impressive but can you be more precise with the measurements?

Yes! The standard Radiolarian size has been 65 mm on an edge. This puzzle is 88mm on an edge.

Eitan, yes, I think that would be amazing if I can do it! I'll try for sure.
