iv drip clamp 3d model

Design a **compact 3D-printable smart IV drip flow cut-off device** that automatically stops fluid flow in an intravenous tube using a servo-driven clamp mechanism. The system should consist of a rectangular main housing approximately 60 mm long, 40 mm wide, and 45 mm high with 3 mm wall thickness, optimized for FDM 3D printing using PLA or PETG. Inside the housing, include a mounting cavity for a small micro servo such as a Servo Motor SG90, with side screw holes and a channel for routing the servo wires. The servo should control a rotating clamp arm connected to the servo horn that moves between open and closed positions (0–180° rotation). The IV tube passes through a curved tube channel designed to support tubing with an outer diameter between 3 mm and 6 mm, with smooth rounded edges to prevent damage. Opposite the tube channel, design a fixed compression block, while the moving clamp arm presses the tube against this block using a removable silicone or TPU pad (3–5 mm thick) placed
