你是否因为设计的模型孔轴配合时无法装配而苦恼，你是否想知道自己打印机的打印精度和误差，这个模型可以让你测试出孔轴配合时过盈配合、间隙配合、过渡配合的尺寸设计参数，实际感受不同尺寸配合时的松紧度，更加方便你的设计
Have you been troubled by the inability to assemble the designed model hole and shaft during fitting? Do you want to know the printing accuracy and error of your printer? This model can allow you to test the size design parameters of interference fit, gap fit, and transition fit during hole and shaft fitting. You can actually feel the tightness of different size fits, which is more convenient for your design.
