About this 3D model

The method for calculating the support angle is: The angle threshold Y of the support circular bottom is: Y = arccos((50-X)/50); X = Z - 30; Z is the acceptable height (mm) of the printed circular bottom) Recommended calculator website: https://mathsolver.microsoft.com/zh/trigonometry-calculator The printing effect of this model is directly linked to the layer height; If the cone below is considered too long, it can be truncated appropriately, but the 30 in the formula X = Z - 30 should be changed to the height of the truncated cone, which can be viewed in the G-code preview; If the model is scaled, the percentage of scaling needs to be multiplied in front of 50 X Z 30.
