This 3D-printable adapter allows you to connect the xTool F1 Desktop Air Purifier exhaust hose to any standard 4-inch dryer vent or HVAC window exhaust kit, making it easy to safely vent laser fumes outside. The F1 purifier hose fits snugly into the adapter, and the assembly can be secured to the window panel with a small amount of superglue or hot glue for a solid, airtight fit.

I used the window exhaust kit linked below, but any kit with a 4-inch opening should work perfectly:

This adapter provides a cleaner, more professional solution for managing laser exhaust. No custom ducting or complex mods are required. If you print or remix this design, I’d love to see your setup!
