OpenSCAD Icicle string generator / maker

This is an OpenSCAD routine to generate strings of icicles for decorative uses, it works especially well if printing in translucent PLA. By editing the SCAD file you can specify how many icicles, of what size and angle. The program generates a new unique string of icicles each time it's run so if you get one you like be sure to output the .STL straight away as next time it's opened it'll change again! Please always check the string before beginning to print as certain combinations of values can result in a string with gaps.
