Okay, so it's not entirely quadratic, there's a sine curve multiplied in there, too! Who can you trust in the face of such deception?! Specifically, we're talking about the side profile shape, here.
Regardless, it's a vase! And a twirly one! Hardly the most original shape, but I like it :)
Mostly, I wanted to work out how I could perform a linear extrusion in OpenSCAD that used a function to define scaling, and overcome the restriction of constant scaling. And, I did indeed find a solution! The code is attached along with the STL file, but be warned, there's no consideration of computational efficiency, and extruding a complex profile quickly ramps up the time required for the final render.
As a vase-mode (Spiralize Outer Contour in Cura) print, this shouldn't cause too many problems. The bottom curves under fairly sharply, which could challenge prints with a smaller nozzle, but there are two easy solutions to this:
* Scale the whole thing up vertically; or
* Lower the model in the slicer as far as necessary to get achievable angles.
All that said, the print in the photos was printed with a 0.4mm nozzle, and it came up just fine :)
