料架1和料架2可单独使用安装，不需要额外螺丝。

料架1和料架3可以组合使用需要另外准备两颗M3*10 螺丝，并配合外9内3.5的垫圈柱使用

我使用的是PETG100%填充，可根据个人情况改变

Shelf 1 and Shelf 2 can be used and installed separately without additional screws.

Shelf 1 and Shelf 3 can be used in combination, requiring two additional M3*10 screws and matching washer posts with an outer diameter of 9mm and an inner diameter of 3.5mm.

Currently, I am using PETG material with a 100% infill rate, which can be adjusted according to individual actual needs.
