6" to 4" Ventilation Duct Adapter
Born out of a need to properly vent an ABS printer whilst utilizing an existing 6" duct, this adapter can be adapted to your needs.
This 6" to 4" ventilation duct adapter is a ready-made transition piece for connecting 4-inch ducting to an existing 6-inch duct or vent opening. It was originally created to vent an ABS printer through an existing 6-inch duct, making it a practical fit for printer enclosures, workshop exhaust, and other ventilation setups where the duct sizes do not match.
The design is intended to print without supports and uses a smooth transition shape to keep airflow moving cleanly through the adapter. If you need a different size, different fit, or a wall-mount version with adjustable dimensions, use the Customizable Wall Mount Duct Adapter.
