Coin Engraver Fume Extractor – 4" Window Vent System (3D Printable)

This compact, high-flow laser fume extractor is designed to direct smoke and odors straight out a window using a standard 4-inch vent hose, keeping your shop air clean and your laser optics clearer during engraving and marking jobs.

Optimized for engravers using standard fiber laser beds, this low-profile extractor is ideal for coin engraving, flat parts, and short-height projects where a full enclosure or bulky extractor isn’t practical.

The design mounts directly to common laser bed rail patterns and channels fumes efficiently outside—helping improve engraving quality and visibility while you work.
