This is a rounded cube model of 100 x 100 x 100mm, which can help us understand the perspective and tactile sensation of different sizes of rounded corners, and assist us in selecting which size of rounded corner to use when modeling.

I used a DLP 3D printing device to print the model, which resulted in a smoother surface. I have uploaded the STP format model, and you can also edit the model according to your own needs.

这是一个100 x 100 x 100mm的圆形立方体模型，可以帮助我们理解不同尺寸圆角的视角和触感，辅助我们在建模时选择使用哪种尺寸的圆角。

我使用DLP 3D打印设备打印模型，使表面更光滑。我已经上传了STP格式的模型，您也可以根据自己的需要编辑模型。
