Prompt
Design a compact, 3D-printable mist spray nozzle optimized for a low-pressure 3–5V DC micro water pump. Mechanical Interface: - The nozzle must be an internal press-fit connector for flexible tubing with inner diameter 5.54 mm. - Inlet outer diameter: 5.55 mm (tight friction fit, tolerance ±0.05 mm). - Include a slight 0.3 mm chamfer at the inlet edge for easy insertion. - Inlet length: 10 mm minimum for secure grip. Overall Geometry: - Total nozzle length: 18–20 mm. - Outer body diameter: 8 mm. - Minimum wall thickness: 1.2 mm throughout. Fluid Path Design: 1. Converging section: - Smoothly reduce internal diameter from 5.55 mm to 1.5 mm over ~8 mm length. - Use a continuous conical or curved transition (no sharp steps). 2. Swirl chamber: - Cylindrical cavity: 3 mm diameter, 2 mm height. - Positioned just before the outlet. 3. Tangential inlets: - 2 or 3 micro-channels (0.8 mm diameter each). - Enter the swirl chamber tangentially (offset from center) to induce
