A few pics

Just a few pics of recent models I've done. W-58 done in a poinsettia styling and coloring. With, and without stamens added

Very nice! Looks very accurate too. Keep up the good work

Here's a W-76, the Rhombidoecadocecahedron approximately 23 inches tall, with each parallel plane a separate color (I think this was 23 different colors). I completed it about a month ago. It's too bad that the photos in the book "Polyhedron Models" by Wenninger aren't in color. Black and white just doesn't bring out the details.

Also nice. Wow, it's big. I tend to make models about as small as workable, which generally means shortest edge between 0.5 and 1 cm.

I haven't made either of your models, I would make this model with about 16cm diameter, or 6.3 inches. About a quarter the size of yours.

The smaller they are, the more I can fit in a display case Big models are great though if you've got somewhere to store them.

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.

I think I should have gone for smaller, as you say it is hard to store. I thought about giving it to a classroom, thinking that they might have more room, but my daughter wanted it for her home. You may have noticed some creases. The pentagrams (stars) are the weak areas. I reinforced some of them with a thicker star glued to the interior, but I didn't like the way it deformed the surface. I also tried paper plates glued internally to the tabs. This seemed better.

Yes, a very nice model. Makes me want to reach for the glue...

Just completed this. I was fooling around with some of the 4D built in .stel files, and came up with this. I'll send the file next.

[Robin Adair]

Here's that file.

Nice work, Robin!

Just finished my first compound, a tetrahedron, cube, and dodecahedron. Here’s a few pics:

I remember seeing a compound of 14 cubes in a book, years ago. I would like to try that next. Thinking on it, I believe the 15th cube would match the positioning of the first cube (with a different face at that position). This indicates to me that each successive cube should be rotated 6 degrees in each of two planes. Any ideas for how this could be done?

[robertw]

14 cubes? They couldn't all fit into the symmetry group the same way.

Stella has compounds of 6 and 8 cubes in its library. You can blend these together (make sure the scales match!) to make a compound of 14 cubes:

[Robin Adair]

Yes, this was in the early 1970’s; I wish I could remember what the book was. I was interested, but (considering the methods of the time) I felt it would have been more work than I was willing to expend.

I really want to thank you for your program ,making it so much easier. Back in the day, using a protractor to measure small prints, making an enlarged version, pushing pins through several sheets of construction paper (not as stiff as card stock), and the poorer glues available to me, between the time and effort of all this, it was easy to get overwhelmed. And, of course, the results were not as good.

You can also put together 1, 3, 4, and 6 to get 14 cubes. This looks as follows:


In that case you will not be able to the the 15th of course

Here I used the 6 | S4xI /D2xI version, there is also a version 6 | S4xI / C4xI where you have a rotational freedom. In that case I would use an angle that will evenly divide when adding the extra cube, i.e.mu=30 degrees.... Hmm, actually because to the classical compound of 3 cubes, one more is added to that plane. That means that mu=22.5 degrees would be even nicer.

Here is how that looks like


Here it is actually the compound of 11 cubes that looks quite nice.
