Cubic Fractal Sides&Edges rounded

I combined the code from my last two fractals and this is the result.
Changing the size_decrement parameter in the scad file yields bulkier/skinnier versions.
rounded14_fractal_2_err_.stl was the result of a mistake I made in the script, that connected some points to the center instead of the parent, but I liked the result, so I uploaded it anyway.
