为了方便大家调整尺寸，我已经上传了solidworks源文件！

For the convenience of adjusting the size, I have uploaded the SolidWorks source file!

请确保你购买的 pvc 管内径和外径与模型一致。这一点非常重要。可以通过调整xy 孔洞补偿来调节模型孔位的大小。当然，你也可以直接修改原文件的尺寸。

Please make sure that the inner and outer diameters of the PVC pipe you purchase match those of the model, This is very important. You can adjust the size of the model's holes by compensating for the “xy-holes-contour-compensation”. Of course, you can also directly modify the dimensions in the original file.

希望你喜欢~
Wish you like it.
