spiral vase 3d model

“Design a minimalist, 3D-printable vase based on a single continuous upward spiral geometry. The form should be generated by rotating a base circle or polygon around the vertical axis while simultaneously lifting it along Z, creating a smooth helical ascent (like a controlled architectural helix). The spiral should complete 1 to 2 full turns maximum, with constant or slightly easing pitch (no abrupt curvature changes). Maintain uniform wall thickness (2–4 mm) and ensure the structure remains watertight and manufacturable without supports if possible. The base must be stable and flat, gradually transitioning into the spiral motion. The top should resolve cleanly into a simple circular or slightly elliptical opening. Avoid any surface detailing, perforations, or secondary geometry. Overall aesthetic: monolithic, parametric, architectural helix reduced to pure geometric motion, resembling a simplified spiral tower or kinetic column.”
