Re: Genus-41 Stewart toroid

Great model! Pretty paper, pretty colours, precise work.

Are the dodecagons and the decagons of the convex hull regular?

Re: Solved twisty puzzle

Oh, that‘s cool and I willingly believe that it is great fun to create such things. „Treat“ is my favorite and I think there is even some King Crimson shining through.

Re: Solved twisty puzzle

This looks like a really huge attainment, congratulations!
These Rubik‘s-like puzzles are much too hard for me and they take far too much time.
And I must confess that I‘d rather see you working on new features in the Stella program :wink: :D

all edges of equal length

Robert,

Is there a trick to trim all edges to the same length?

Re: large model

Unusual nice colouring!
If that‘s a normal cup, the edge length should be about 50 cm?

Re: A few pics

This is one of my favourite uniform polyhedra and I like your model very much.
I once made this shape too but only with three colours. That‘s not really satisfying.

Re: Work in progress

The diameter will be 396 mm. You‘re right, the pattern is based on the stellation diagram. A laser cutting machine works well and can accelerate the process a lot. I could gather some experience in the past. The results are very precise but a little „sterile“. And although it can be rather painful, ...

Re: New Torus

You should have a look at Alex Doskey‘s website. He studied Stewart’s book thoroughly and he has lots of such toroids:

This is the sixth stellation of my model of the great snub dodecicosidodecahedron, which is No. 115 in Magnus Wenninger‘s book „polyhedron models“. Nine further stellations are to come. The edge length will be 30 cm. There are 15 colours, 6 for the snub triangles, 5 for the icosahedral triangles and...
