parameterized hexagonal mesh

thingiverse

This model is a parameterized hexagonal mesh. I offer it primarily for training purposes with OpenSCAD. This code was written intended as a negative in another object skills demonstrated in this code: - looping with `for` - if - rotate - translate - using cylinders with $fn=n$ as regular n-gons - modules calling modules - default argument values amazingly, this code doesn't use any globals! --- suggested exercises: - modify the code so that it lets you specify any number of columns, not just pairs of them - modify the code so that the thickness of the hexes is a function of their position in the grid
