打印中有一处多色打印，其余均为单色打印，把手因为3D打印的强度不高并且成本较高，所以把手部分可以选用20mm直径的PVC管材。把手上可以缠绕黑色手柄防滑胶带增加质感。

There is a multi-color printing in one area, while the rest is monochrome printing. Due to the low intensity and high cost of 3D printing, PVC pipes with a diameter of 20mm can be used for the handle part. Black handle anti slip tape can be wrapped around the handle to increase texture.
