The prompt
Create a precise, lightweight, 3D-printable one-piece X-shaped mini quadcopter chassis for four 8520 brushed motors. Dimensions (mm): - Motor-to-motor diagonal: 105 mm. - Overall size: approximately 135 × 135 mm. - Central deck: 36 × 36 mm. - Arms: 6.5 mm wide × 2.6 mm thick. - Four integrated circular propeller guards: 32 mm outer diameter, 1.6 mm wall thickness, 5 mm height. - Motor mounting collars: 8.7 mm nominal internal diameter. Use PETG-compatible geometry with rounded corners, strong arm-to-guard connections, and minimal material. Include four 30 × 30 mm flight-controller mounting holes. Target bare chassis weight: 17–20 g. Make the entire frame and four guards one connected printable part. Ensure symmetry, accurate dimensions, watertight geometry and no unnecessary decorative components. Deliverables: Export a genuine 3D model as STL and STEP, plus an interactive 3D preview. Do not generate just an image.
