Hexagonal Fractal

This is a not so often seen hexagonal fractal.The question was:What is the simplest 2D fractal with hexagonal symmetry under the constraint that it would make a reasonably sturdy structural material when stopping iterations at some point.That means the wakest points should scale with iterations tooactivate line with a=30° for sturdy configurationactivate line with a= 0° for weak configurationedit:If you start asking that same question in 3D instead of 2D you'll get tetrapods out of tetrapods out of tetrapods and so on.like this here:http://www.thingiverse.com/thing:13786 --- Imported from Thingiverse: https://www.thingiverse.com/thing:14023 Original creator: mechadense
