Hi Non-Twisty Puzzles fans,

Penta Beams is a geometric construction puzzle in the shape of a triangular pyramid, made of five pentagonal beams woven through each other. The object is to take the structure apart and put them back together again.

Watch the YouTube video.
Buy the puzzle at my Shapeways Shop.
Read more at the Shapeways Forum.
Check out the photos below.

Enjoy!

Oskar

How does this relate to the earlier Star Beams puzzle?

One could consider them shape-mods.

Interestingly, for the first time ever I can say that Oskar's pentagonal stick puzzle is a simple one!!! :lol: :lol:

My friend Steve Nichols has been 3D printing for a long time and recently produced this for me. It is based on pentagonal parts and is extremely difficult to assemble. My version is made easier by having 5 sticks of the same colour pointing in each direction.

You didn't need to tell us it was extremely hard to assemble. :D
It looks that way. :shock:

Has there been any correct answer to the question in the video?

Does you friend Steve Nichols have a Shapeways page? You should talk him into offering this there.

He is making them himself on his own 3D printer and I suspect they will be seen in large numbers at the upcoming International Puzzle Party. I doubt he will be making them available on Shapeways yet but I'll point him at this thread (he is registered with TP) and let him reply for himself.

Thanks for posting the picture Kevin. :D

As you mention so far all copies of this puzzle have been printed on the 3D printer I make and sell with another puzzler Simon Bexfield (www.threedyprinters.com)

You can read more about the puzzle over at James Dalgety's website (http://puzzlemuseum.org/) James, still has few remaining exchange copies for sale which were exchanged at the last IPP in Japan. I suspect I will have one or two for sale at the forthcoming IPP...

I've only printed one copy so far with shapeways but may release the design there in a few months - will post here when I do (starting a new thread rather than hijacking this one :? )

Steve

P.S. Kevin are you *sure* the colours make it easier?

I have a wooden variant of this puzzle, although obviously not with pentangular cut pieces.
Yes, you need big hands to hold this sphere when assembling :)

I don't know who made it, does anybody here have an idea?

It is called the Square rod dodecaplex!
http://home.comcast.net/~billcutler/stock/dodecaplex.html

It was originally designed by the great Mathematician and puzzle designer Bill Cutler in 1978 and made by the amazing Tom Lensch. They were huge at 10" across and are not available any more. Yours does not look like one by Tom and may be a copy made by another company (it has the look of a Philos puzzle but I don't know whether they ever made it.

Bill's description says:
Quote:
The rods in this puzzle should more properly be pentagonal in cross-section, but this would be harder to manufacture.

Only now that 3D printers are available are pentagonal sticks now easily made.

Thanks a lot for the details!

I guess mine is a commercial copy from a X-mas fair or so..
The sticks are 10 x 1.5 x 1.5cm, puzzle diameter 13cm. Weight 369g.
