这是一个转珠手球，在无聊的时候、思考的时候，可以拿在手中把玩。由于3D打印机的局限性，无法很好的一体成型打印这个玩具，主要是球体如果直接打印的话，会很容易翘曲。因此我将模型分成了两半，这样能够得到更好的打印质量。

1、请开启支撑进行打印。
2、打印完成后，请使用工具将支持移除（这一步需要一点耐心）。
3、组合球体，这里建议用胶水将球体进行粘合。
4、建议用砂纸对Z缝、球体进行打磨，让它尽可能的光滑（不打磨也可以）。
5、将小球放入外环中，然后完成另一半外环的粘合。
6、OK，现在您可以尽情拿在手中把玩了。

This is a spinning ball that can be played with in your hand when bored or thinking. Due to the limitations of 3D printers, it is not possible to print this toy in one piece, mainly because if the sphere is printed directly, it will easily warp. Therefore, I divided the model in half to achieve better printing quality.

1. Please turn on the support for printing.

2. After printing, please use the tool to remove the support (this step requires some patience).

3. Combining spheres, it is recommended to use glue to bond the spheres together.

4. It is recommended to use sandpaper to polish the Z-joint and sphere to make them as smooth as possible (without polishing).

5. Place the small ball into the outer ring and complete the bonding of the other half of the outer ring.
