RhoDoDe (Heinz Strobl)

Designer: 
Strobl, Heinz
Folder: 
Adams, Sara
Difficulty Level: 
Low intermediate
Model type: 
Modular

I looked through the newest BOS issue today, and discovered that Heinz Strobl contributed diagrams to his rhombic dodecahedron. I decided to give it a try.
Which means I first had to cut lots of paper. 24 strips with ratio 1 by 2, 24 strips with ratio 1 by 5, and 12 strips with ratio 1 by 8. Ugh! Then some boring folding, which are much easier using Heinz's suggested "tool" (another strip of paper), and finally assembly. Altogether it's not a hard model to complete, but it requires patience. Making this model brought a bit closer how much work Heinz Strobl puts into his large creations. Admittedly, I found the cutting to be the most tiresome part, and I know that Heinz has rolls of paper, so that he only needs to crop to the right length. That should save lots of time (i.e. the time I needed for making strips in the first place).
Altogether I think it's a very pleasing model. The diagrams focus on the assembly, and they are, while relatively minimal, absolutely sufficient. And that's from someone who's known to curse when assembling most modulars. Talking about modulars, this piece is modular in that you need several strips, but the modules are quite different. I'd say the 1 by 8 strips are similar to modules, the 1 by strips are hinges, and the 1 by 2 strips are stabilisers, as well as cover-ups for some of the raw edges. Heinz calls this kind of work snappology, somewhat in contrast to his knotology.

Paper: 24 x 1.8cm by 3.6cm, 24 x 1.8cm by 9cm, 12 x 1.8cm by 14.4cm, blue Korean origami paper (relatively heavy, doesn't like being creased too much - i.e. horrible for most projects)
Model: sphere with a diameter of approx. 7.5cm

Have you tried to figure out how to connect the Rhodode together yet?
By the way, I already created mine as well, but it's probably not exact as the assembly you described.
Another BTW, isn't the 1 by 2 supposed to be 1 by 3 because if it was a 1 by two, the strip would probably fall off.

What do you mean by "connect together" - the picture shows my completed RhoDoDe, so, yes, I know how to assemble it.
As to whether I assembled it exactly as shown in the diagrams - I think so. Obviously you have some room for variation, as in how you insert each strip, but other than that I think if you go wrong it won't work out.
Finally, a 1 by 2 strip works for the locks. I actually think 1 by 3 would be counter-productive. The locks are very stable, and there's no risk of them falling of in my completed model.

Hope this helps,

Hm, it doesn't look that hard. Instead of adding a strip to close the sphere, open it up wider again and start the next sphere. I actually added one strip in the wrong place when I started assembling, you only have to position it somewhere else.
I'm not in the mood to cut more strips and try it out, but I'm sure it'd work out ok for you.

where cani find the diagram or the video for this rhodode ..?

I don't think there is a video on this model. I found diagrams for it in the British Origami Issue 258 (October 2009), which all members of the British Origami Society received. I think it's the first time the diagrams have been published.
