I am interested in creating a (3d printed) sudoku board...
I wanted to start with (something like) a 9-sided dice.
I think that if you 'sliced' 9 flat faces into a sphere you'd get something like it. :) The faces would need to be the same size and equidistant; which sounds simple. But, my mathematical knowledge isn't good enough for this.
I've been using Open SCAD for modelling; and have created a Dodecahedron (12 sided regular polyhedron); and I guess this would be OK - with 3 "black" faces.
Your idea of creating a 9-sided dice for a sudoku board sounds really interesting. While I'm not a math expert myself, I can suggest checking out some online resources or forums where you can find guidance on creating such a shape. By the way, during my online browsing, I stumbled upon this website flipsimu.com. It's a d12 roller that might come in handy for your project. Give it a look! Feel free to keep us updated on your progress and ask for more suggestions. Oh, and just a heads up, I'm new here on the forum. Good luck with your dice creation, and have fun with your sudoku board!
