S1C PTFE Protector 铁氟龙管保护罩

A simple but effective PTFE tube protector that prevents PTFE tube from rubbing against the print head front casing, causing wear and tear and even breakage. Just clip it into the PTFE tube and position the small concavity against the casing (see the pictures for reference). 简单有效的PTFE保护罩，可以防止PTFE管由于反复摩擦打印头模块前盖导致的磨损，甚至磨穿。打好后直接卡在PTFE管子上并确保凹陷的地方朝向打印头外壳（参考上传的图片）。
