我设计了一个scoop，用来配合我设计的丝杠保护罩（链接在这里：https://makerworld.com/zh/models/501786）。它可以对保护罩下端进行限位，确保保护罩不会变形，从而影响到打印平台。我使用PETG打印保护罩，在255°/80°，封箱打印的环境下，使用了半年没有出现问题。需要支撑，spoiler的翻边比较薄，拆除支撑的时候需要小心。

I designed a scoop to work with the lead screw shields I designed (you can find it here: https://makerworld.com/zh/models/501786). It can limit the lower end of the shields. So that the shileds will not move and affect the printing platform. I used PETG to print it. At 255°/80°, door closed printing environment, it has worked for half a year without any problems. Support is required. The spoiler flange is relatively thin, so be careful when removing the support.
