使用SolidWorks建立真實的螺紋與螺帽，並運用數學關係式來達到參數式繪圖。
3D列印時不要使用支撐，以及速度最好放慢一點，列印完成後不需要再修整零件，
一般的公制英制螺絲都適用，可以與實際的螺絲螺帽做搭配，變化性高。

Use SolidWorks to create realistic threads and nuts, and use mathematical relationships to achieve parametric drawing.
Do not use the support when 3D printing , and the speed should be slowed down a bit. After the 3D printing is completed, it is not necessary to trim the parts.
The general metric inch screws are suitable for use with the actual screw nut, and the variability is high.
