The prompt
Design a fully functional 3D printable IV tube clamp with a servo-controlled flow control mechanism. The design should consist of: - A fixed bottom clamp with a semi-circular groove for holding a flexible IV tube (3–5 mm outer diameter). - A movable top clamp that moves vertically to compress the tube. - The top clamp should be driven by a standard SG90 micro servo motor using a servo horn connected to a pivoting lever. - Include a hinged mechanism so the servo rotation converts into vertical linear motion. - Add textured serrated gripping surfaces inside both clamps to prevent tube slipping while allowing smooth flow regulation. - Four screw holes at the corners for assembly using M3 screws. - Separate printable parts for easy assembly: 1. Bottom body 2. Top movable clamp 3. Servo mount 4. Pivot arm 5. Servo linkage 6. Side supports - Designed for FDM 3D printing with PLA. - Print without supports whenever possible. - Wall thickness around 2–3 mm. - Mechanical tolerances of 0.25 mm between moving parts. - Compact dimensions approximately: Width: 60 mm Height: 45 mm Depth: 35 mm - The servo should mount flush to one side with accessible mounting holes. - The mechanism must smoothly adjust IV tube compression from fully open (maximum flow) to fully closed (minimum flow). - Include realistic mechanical joints and assembly-ready geometry suitable for Fusion 360, SolidWorks, or STEP format. - Engineering-grade mechanical design with clean edges, fillets, chamfers, and proper clearances.
