YAFN – Yet Another Filament Nest
This small adapter mounts on the AD5X toolhead and provides a convenient place to install a standard 4-tube IFS filament channel.
It allows quick switching from the IFS system to direct filament feeding, which can be useful when printing very soft filaments that may struggle with longer filament paths.
The mount keeps the filament path short, stable, and aligned with the extruder.
Features
Mounts directly on the AD5X print head
Holds a standard 4-tube IFS filament channel
Enables direct filament feed
Useful for very flexible materials
Simple and compact design
Installation
Installation requires a standard computer fan screw:
M3 × 30 mm
This screw type is very common and often used for PC fans and water-cooling radiators.
Steps:
Place the mount on top of the print head.
Insert the screw through the mount.
Secure it in the existing mounting point.
Insert the IFS 4-tube channel into the holder.
When to Use It
This setup is helpful when printing materials such as:
very soft TPU
flexible filaments
specialty materials that prefer a short filament path
It allows temporarily bypassing the longer IFS routing while keeping everything clean and organized.
