使用自动朝向，将文字倒置摆放打印。Use Auto Orientation to print text upside down.

当使用模型编辑器时，修改文字，但是只能输入英文文本，因为我现在还不是很会用这个，笑死我了。注意横的支撑要覆盖全保证文字支撑全。好像在说废话。When using the model editor, change the text, but only enter the English text, because I don't know how to use this yet, and I laugh at it. Note that the horizontal support should be fully covered to ensure that the text is fully supported. As if talking nonsense.

由于打印机精度不尽相同，为了达到完美的配合，我设置了可编辑的安装孔尺寸，默认半径是1.85mm，用和可自定义半径，建议范围在1.8mm~1.9mm间。Due to the different accuracy of printers, in order to achieve a perfect fit, I set an editable mounting hole size, the default radius is 1.85mm, with and customizable radius, the recommended range is between 1.8mm~1.9mm.
