Monoedre

The monohedron is a three-dimensional surface obtained by applying two simultaneous rotations to a regular convex polygon, such as a square or a hexagon. The result is a curved surface with a single face that can have a variety of different shapes depending on the rotation parameters used. https://www.youtube.com/watch?v=NCaoYQCAFT4
I provide 3 models generated by an equilateral triangle, a square, and a pentagon. I can make the shape you want.
I wrote a Python script that generates the OpenSCAD file that creates the STL file.
