Extrude-Scale by Function: Ribbons
thingiverse
The positioning and angle of each extrusion in the base shape (a square, although any 2D form can be used) is controlled by one equation per axis, plus a scaling equation. This totals seven user-defined functions that can be customized as desired. While this particular shape has no practical use (except perhaps for creating unique pasta), it demonstrates OpenSCAD's ability to create flowing, organic shapes. It reminds me of the work I did with TopMod a few years ago. If you want to experiment further, feel free to play around with the OpenSCAD script and check out the GitHub repository at github.com/syvwlch/Thingiverse-Projects/tree/master/ScaleExtrudeHorns. And don't forget to have fun!
