Bambu Dual Extruder Idlers and Filament Sensor

This integrated replacement unit is specifically for the Bambu H2D/H2C dual extrusion system. It combines two critical functions:

Idlers: Provides the necessary tension and guidance to press the filament against the extruder gears.

Filament Sensor: Detects the presence and movement of both filaments to alert the user of run-out or blockage.

Replacing this unit ensures reliable feeding tension and accurate filament run-out detection for smooth dual-material printing.
