glass greenhouse 3d model

Create a 3D model of the Curitiba Botanical Garden greenhouse (Jardim Botânico de Curitiba), optimized for FDM 3D printing. The model should accurately represent the iconic glass-and-metal greenhouse inspired by Art Nouveau architecture, featuring its arched structure, symmetrical layout, and distinctive curved metal ribs. Details should be simplified and reinforced to ensure printability while preserving the recognizable silhouette. Windows and glass panels should be represented as solid surfaces or shallow recesses, avoiding thin walls or open lattice structures. Structural elements such as arches and frames must be thickened and connected for strength. Technical requirements: Watertight (manifold) model Minimum wall thickness ≥ 1.2 mm No unsupported floating parts Overhangs limited to ~45° or designed to be self-supporting Solid geometry (not hollow) Integrated flat base or platform representing the ground Single-piece model suitable for standard FDM printers Scalable design (e.g., default width
