Angular Bent Hollow Tube

Create a 3D CAD model of a hollow cylindrical tube with an angular, bent profile, matching the uploaded reference sketch. **Geometry and dimensions:** - Long side: 150 mm. - Short side: 120 mm. - Hollow center bore: 19.75 mm diameter. - Outer diameter: 27.75 mm, resulting in a nominal 4 mm radial wall thickness. - Cross-section: circular, with a constant outer diameter and inner bore along the entire length. - Shape: follow the angular outline in the reference image, with straight sections connected by distinct angled bends. Reproduce the general proportions and silhouette shown. - The tube must follow the bent path rather than being a straight cylinder. **Ends and openings:** - One end must be completely closed with an integrated solid end cap. - The opposite end must remain open, with the 19.75 mm bore accessible from the outside. - Ensure the closed end has no accidental hole or opening. - The internal bore must terminate at the closed end cap. **CAD requirements:** - Use millimetres. - Create one continuous, watertight solid. - Maintain a constant 27.75 mm outer diameter and 19.75 mm inner diameter throughout the tube, except at the closed end cap. - Make all bends smooth enough to avoid self-intersections while preserving the angular appearance of the reference. - Keep the dimensions and bend angles editable. - Ensure the model can be exported as an STL for 3D printing. Prioritize dimensional accuracy and the reference silhouette over decorative details. Do not add grips, textures, flanges, threads, or other features that are not shown in the reference image.
