Description
A parametric round vent cover / vent grill for 3D printing that fits any diameter and supports multiple airflow styles— slat grille (like common HVAC/extractor vents) , grid, holes, or a fully sealed cover.
Designed as a round insert vent with a clean front flange and a cylindrical spigot for a snug fit in ducts, wall holes, cabinets, electronics enclosures, and DIY ventilation projects. Optional countersunk mounting holes are included for flush screw mounting.
Customizer inputs (simple):
- Outer diameter (front flange)

Plus: pattern selector + optional countersunk holes.
Great for: HVAC wall vents, bathroom/extractor vents, fan grills/guards, duct covers, cabinet vents, speaker-style vents, electronics enclosure ventilation, or sealing unused holes.
Print in PLA/PETG for general use, or ABS/ASA for warmer airflow areas.
