FILAMENT SENSOR LEVER BL MK3S MK2.5S

The Prusa PETG Filament Sensor Lever for MK3S and MK2.5S is a high-quality replacement part manufactured from durable Polyethylene Terephthalate Glycol (PETG). This material is renowned for its exceptional toughness and impact resistance, making it an ideal choice for mechanical components subject to regular stress in 3D printing operations. Compared to standard PLA, PETG offers superior heat resistance and lower warping tendency, which is crucial for the precise fit required of this delicate lever. For printing this part, a nozzle temperature of 230–250 °C and a heated bed temperature of 75–85 °C are recommended. While an enclosed build chamber is not strictly necessary, it can further enhance print quality, particularly for larger models. PETG is hygroscopic, so drying the material before printing is advised to achieve optimal results. This lever is specifically designed for use with Prusa MK3S and MK2.5S printers, ensuring reliable operation of the filament sensor. Key strengths of PETG include its chemical resistance and excellent layer adhesion, while its limitations include a slightly higher tendency for stringing, which can be mitigated through appropriate retraction settings. This replacement part is an excellent choice for users seeking to maintain the longevity and reliability of their printer.
