ipad mini stand 3d model

Generate a clean, functional 3D model of a modular stand for the iPad Mini (2024). The design should have precise, geometric shapes suitable for FDM 3D printing. Include three separate modules: 1. A wide, stable base with a flat bottom and optional cable pass-through. 2. A back support arm with a fixed viewing angle of about 60 degrees. 3. A top cradle that securely holds the iPad Mini (2024) in both portrait and landscape orientation. Add simple mechanical connectors between modules, such as dovetail joints or cylindrical sockets for screws. Avoid organic shapes. Use straight edges, flat surfaces, and CAD-like geometry. The model should be watertight, printable without excessive supports, and structurally strong. Remove the actual iPad, keep the rest.
