ventilation cover

This is a 3D-printed ventilation cover designed for 100mm (10cm) duct openings. The cover features a cylindrical shape with a solid flat surface to effectively block airflow when needed. The outer edge is slightly raised to fit snugly over the duct opening, ensuring a secure placement.In the second image, the cover is installed over a ventilation duct, secured using a metal clamp, making it easy to remove or adjust as required. The bright yellow-green color enhances visibility, and the 3D-printed construction suggests it can be customized in terms of material and size.This cover is ideal for sealing off unused ventilation ducts, preventing drafts, dust, and pests from entering through open vents.
