Description
Modular Window Vent System for 3D Printer Fume Management
This modular window vent system is designed to help manage fumes when printing indoors with enclosed 3D printers.
The system allows you to mount a standard 120mm PC fan and exhaust air through a 4 inch duct hose directly outside through a window opening. Unlike foam board inserts or temporary cardboard solutions, this design uses rigid, mix and match extension modules to create a clean, secure, and adjustable fit.
Built for makers running enclosed printers and higher temperature materials.
