Celtic Knots for openscad
thingiverse
My child desired a Celtic knot bracelet, so I utilized this library for my initial attempt. It includes some sample patterns at the top. The latest version is available on GitHub at https://github.com/beanz/celtic-knot-scad, but be aware that the API is still under development and may change soon. Please provide feedback to help solidify the API more rapidly. In future, I plan to create a Celtic knot font of the tile alphabet for http://www.thingiverse.com/thing:16193, enabling us to "draw" knots on cylinders and spheres too. UPDATE 2014/02/02: I've removed the use of children(), which isn't supported in older versions of OpenSCAD.
