Miniature Belt Conveyor Assembly

Create a **functional miniature industrial belt conveyor for 3D printing**, approximately **180 mm long, 55 mm wide, and 65 mm high**. **Design:** - Industrial-style conveyor frame with two side rails and support legs. - One drive-end drum and one tail-end drum, both mounted on axles and able to rotate freely. - A continuous flexible belt loop running around both drums. - Several small freely rotating support rollers under the upper belt run. - Two or more return rollers under the lower belt run. - Realistic mechanical construction inspired by industrial bulk-material belt conveyors. - No motor, no gears, no electronics, no decorative covers. - The belt must be moved manually by pulling it with a finger. The drums and rollers must rotate freely. **3D-printing requirements:** - Design the frame, drums, rollers, axles, and belt as separate components where possible. - Use simple, robust geometry suitable for FDM 3D printing. - Use cylindrical axle holes and separate axles for rotating parts. - Provide approximately 0.3–0.4 mm clearance between moving plastic parts. - Avoid supports where possible and avoid thin, fragile details. - Use a flexible TPU belt, or design a simple belt loop that can be made separately from a thin flexible material. - Suggested axle diameter: 2–3 mm. - Suggested frame thickness: 3 mm. - The model must be mechanically plausible and assembled from printable parts. **Important:** Prioritize correct mechanical geometry, separate printable parts, and free rotation over visual details. Do not create a solid sculpture or a non-functional representation. Generate an editable CAD model with dimensions if supported.
