Filament sensor PTFE 4x2x15 (MINI/+)

The Filament Sensor PTFE Tube (4x2x15 mm) by Prusa Research is a high-quality replacement part specifically designed for use with Prusa MINI and Prusa MINI+ 3D printers. This component is a crucial element of the filament sensor system, which monitors material flow and protects against print failures caused by empty spools. Made from PTFE (Polytetrafluoroethylene), the tube excels due to its excellent sliding properties and high chemical resistance. The inner diameter of 2 mm allows for smooth material transport, while the outer diameter of 4 mm ensures a stable fit within the sensor housing. As this is a technical spare part, no specific printing temperatures or heated bed settings are applicable. The primary application is maintenance and repair of the filament sensor assembly. Its strength lies in precision manufacturing, guaranteeing an exact fit and extending the sensor's lifespan. A limitation is its specific compatibility, restricted to the Prusa MINI series. For optimal performance, the tube should be checked regularly for debris and replaced when necessary to ensure the reliability of the autoload system.
