there we go again, with a #trefoilknot I can easily make sure I defined a moving coordinate frame along the path. What a #rollercoaster. #openscad #3dmodelling

I do like a challlenge, but this is very, very challenging. It's supposed to be the trefoilknot, but somehow I must have taken the wrong direction 😆. I will have to try again.
I never have been good in math in Dutch and in English terms it's even more dificult obviously. For example I have never heard of a knot in math before, only in yarn 😉. But I do get the grips of that's helpfull to understand this kind of math if you can crochet it. Very interesting for math teachers!

The yellow and the purple band form a #trefoilknot.
And together they form a ring.
This was build by composing prisms and anti-prisms.
