cults3d
Playing with Openscad, I created a model for a shell similar to that of nautilus. Two STL files are provided, one for the half of the shell (so that the inner parts are visible), the other for the whole object.
I intend to try other parametrizations for more convoluted shells. This one is a first version, one of the simplest possible.

This STL file is compatible with most FDM 3D printers (Creality Ender 3, Prusa MK3S+, Bambu Lab, etc.) and resin printers (Elegoo, Anycubic). Check the original page for recommended print settings and materials.
This is a premium model priced at on cults3d. Premium models often include higher detail, multiple parts, and print-tested files.
Most STL files can be modified using free software like Blender, TinkerCAD, or Meshmixer. Check the license on the original cults3d page to see if modifications are permitted by the creator.
