***It is recommended to print using the configuration of the file, without making changes to it, except for filament***
The central shaft may need to be polished before it can be assembled properly. If possible, it is recommended to use high-hardness consumables (I used Esun magic dual-color filaments, which are both beautiful and have very high hardness)
The model in the file has multiple color settings. If you don't have AMS, you can also try manually changing the material for printing (only 4 color changes are required), or print a single color
Additional purchases are required: Yo-Yo ball bearings (typically 12.7*6.35*4.76mm in size), and a 19mm outer diameter adhesive sticker or use silicone to fill the area where the adhesive sticker is attached (of course, there are also adhesive sticker models in the file, you can also choose to print it using TPU filament, although it may not be as easy to use as purchasing one)

***建议使用文件的配置进行打印，不要对其进行更改，除了耗材***

中轴可能需要进行打磨才能正常组装，如果可以建议使用高硬度的耗材（我使用了esun的魔幻双色耗材，既好看又有着非常高的硬度）

文件中模型有多色设置，如果你没有AMS你也可以尝试手动换料进行打印(只需要进行4次换色），或者打印单色的

需要额外购买：悠悠球轴承（尺寸一般是12.7*6.35*4.76mm），和外径19mm的胶贴或者使用硅胶填充粘贴胶贴的区域（当然，文件中也有胶贴的模型，你也可以选择使用tpu打印它，虽然可能不如购买的好用）
