Specially designed for you who pursue ultimate printing quality! This semi transparent PTFE tube allows you to see the status of the fine threads inside the tube at a glance, detect and handle any abnormalities in the threads in a timely manner, and ensure accurate printing every time. Specially customized for direct drive extruder 3D printers, such as Bambu Lab series, Ender 3 V3, etc., it is perfectly compatible and easily improves printing efficiency. Adopting a 2.5mm inner diameter design, compared to the traditional 2mm inner diameter, consumables are transported more smoothly, reducing stuttering and improving printing smoothness. Made of high-quality materials, durable and corrosion-resistant, with excellent acid and alkali resistance and high temperature resistance, ensuring stable transmission of fine wires in high-temperature environments and consistent printing results. We have equipped you with a 1.5-meter PTFE tube, which not only meets your daily printing needs but is also easy to carry and store.
