Air duct went reducer 125mm to 80mm/height 100mm

This 3D printable adapter is designed to seamlessly connect a 125mm diameter air duct to an 80mm diameter foil hose, specifically tailored for smoke extraction systems in laser engraving machines. It provides a secure and efficient transition, ensuring optimal airflow while preventing leaks or restrictions in your ventilation setup.

Key Features:

• Precise Dimensions: The adapter reduces from 125mm (outer diameter at the base) to 80mm (outer diameter at the top), with a total height of 100mm. Internal dimensions are optimized for a snug fit with standard foil ducts and rigid pipes.
• Tapered Design: The conical shape promotes smooth airflow, minimizing turbulence and pressure loss during smoke evacuation.
• Material Compatibility: Recommended for printing in durable materials like PLA, PETG, or ABS for heat resistance and longevity in laser environments.
• Easy Installation: Simply slide the 125mm end onto your laser engraver's exhaust port or existing duct, and attach the 80mm end to your flexible foil hose. No additional tools or modifications required.

Why This Adapter?

Laser engraving produces harmful fumes and particles, and a reliable smoke extractor is essential for safety and clean operation. This custom adapter solves the common issue of mismatched duct sizes, allowing you to integrate affordable or readily available 80mm foil hoses with larger 125mm systems. It's a simple, cost-effective solution that enhances your workspace ventilation without compromising performance.

Printing Recommendations:

• Layer Height: 0.2mm for a balance of speed and detail.
• Infill: 20-30% gyroid or cubic for structural strength.
• Supports: Not required if printed upright on the wider base.
• Print Time: Approximately 1-2 hours on a standard FDM printer like the Bambu Lab series.
