Yet another sax reed

Well, I couldn't resist to make my own version of the sax reed. It mainly differs in these things from the source:

- requires less parameters, since no slices are defined but a height-function implemented
- renders quite a lot faster (about 15 secs on a 3GHz machine)

I also had issues with the cited design producing vary small gaps between segments which the slicer (CURA) tried to print.
The scad file includes one of the parameter files for easier switching.
You need the free "dotSCAD" library for the function plotter. Don't know if links are legal here, it is on github.
3 sample parameter files and resulting stl files are included.
Main parameter to make a reed harder or softer is of course the tip thickness. What I called "belly" also plays a role. Just experiment :)

UPDATE:
thanks to MojoBari who let me know the DotSCAD function I used is no longer in the library. I have modified the code to use sf_thicken instead.
I have also replaced the parameter files by my lat
