The prompt
**PROMPT — DRONE LANDING GEAR** Create a highly accurate 3D CAD model of a quadcopter drone landing gear, using the attached reference image as the primary geometric reference. The landing gear consists of exactly two long, parallel cylindrical landing skids connected by two wide, curved structural supports. **Main dimensions:** - Landing skid length: 250 mm. - Distance between the two parallel skids: 240 mm. - Front support height: 105 mm. - Rear support height: 110 mm. - The rear support must be exactly 5 mm taller than the front support, introducing a subtle asymmetry. **Structural details:** 1. Two straight, cylindrical landing skids running parallel to each other, with smooth rounded ends. 2. Two wide, solid, molded support arches connecting both skids transversely. 3. Each support must have slightly inclined, nearly vertical legs, curved shoulders and a short, relatively flat horizontal top section. 4. Add an elongated rectangular mounting slot on the upper section of each arch. 5. The lower ends of the arches must connect cleanly to the cylindrical skids through compact mounting saddles. 6. The supports should resemble molded structural plastic components, with broad surfaces and gently rounded edges. 7. Preserve the distinctive angular-curved silhouette of the reference image. Do not create semicircular arches. **CAD and geometry requirements:** - Generate a real 3D solid, not a surface model or a visual-only mesh. - Use clean, continuous geometry with watertight connections. - Avoid unnecessary details, excessive segmentation, decorative patterns and tiny features. - Keep the structure suitable for finite element analysis (FEA). - All dimensions must be expressed in millimeters. - Ensure the complete assembly is one connected solid body. - Export the final model as STEP and STL. **Visual style:** Industrial drone engineering component, realistic proportions, matte black structural supports, two smooth cylindrical skids, clean CAD geometry, neutral white background, isometric three-quarter view. The most important requirement is to reproduce the exact silhouette and proportions of the supplied reference image. Do not redesign or stylize the landing gear.
