blue pipe elbow 3d model

Create a precise 3D model of a hose adapter with the following parameters: BOTTOM PART (FLANGE + MAIN RING) Outer diameter: 69.5 mm Inner diameter: 56.5 mm Height: 10 mm Flange outer diameter: 48.4 mm Flange thickness: 2 mm TOP TUBE SECTION The tube extends upward from the bottom ring for 90 mm (straight section). At the end of this tube, add a smooth bend of 30–35° (gentle, not sharp). INTERNAL THREAD Add internal hose-type thread only at the very end of the bent section, not along the entire tube. Thread depth: 5–7 mm Thread type: simple spiral “vacuum-cleaner style” guiding ribs (no need for precise ISO standard). GENERAL REQUIREMENTS The model must be watertight and manifold. No self-intersections. The internal channel must remain cylindrical (Ø 56.5 mm) through the straight section and bend. The bend must be generated as a smooth, evenly curved transition with no sharp deformation. Output format: STL.
