The prompt
Design a professional engineering-grade Honeycomb Air Distribution Chamber for a compact environmental monitoring device called PERN V2. The component must be fully manufacturable by FDM 3D printing and optimized for low pressure drop and uniform airflow distribution. Overall Dimensions • External dimensions: 90 mm × 90 mm × 25 mm Wall Thickness • 3 mm outer frame Honeycomb Structure • Hexagonal cells • Cell diameter: 6 mm • Cell depth: 20 mm • Uniform geometry • Rounded internal edges Airflow Requirements • Straighten turbulent airflow coming from a cyclone separator • Uniform airflow velocity across the entire outlet surface • Low pressure drop • CFD-friendly geometry Mounting • Four M3 mounting holes • Alignment pins on both sides • Airtight sealing groove for silicone gasket Connections Front interface compatible with cyclone outlet. Rear interface compatible with removable adsorption cartridge. Manufacturing Support-free FDM printing. Minimum wall thickness 1.2 mm for honeycomb walls. Outer frame thickness 3 mm. Large corner fillets. Material PETG or PLA+. Engineering Goals Improve airflow uniformity. Reduce turbulence. Reduce dead zones. Increase adsorption efficiency of the next cartridge. Professional industrial appearance suitable for commercial prototype development.
