莲花流水摆件，使用的是森森6W水泵，底部孔洞是17.2mm，已上传STEP文件，可以自行修改。我的水缸直径为240mm。

需要树状支撑，中间的支持我保留了，没有拆

The lotus water ornament uses a SenSen 6W water pump, and the bottom hole is 17.2mm. The STEP file has been uploaded and can be modified by yourself. The diameter of my water tank is 240mm.

Need tree-like support, I kept the middle support and did not remove it
