Customizable Wall Mount Duct Adapter

3D printable 4 in duct wall adapter with customizable fit. Secure screw plate design for venting printers or exhausts.

This customizable wall adapter is designed to mount a standard 4 in duct using a strong square plate with four screw holes.

The default model fits ducts with a 116 mm inner and 120 mm outer diameter, but parameters can be adjusted for different sizes or shell thicknesses.

Based on my successful 6 in to 4 in reducer, it offers a reliable, easy-to-print solution for venting 3D printers and other exhaust systems.
