FAQ

What is the difference between a cone and a frustum?

A pointed cone has a top diameter of 0 mm. When both ends have a diameter, the result is a truncated cone, also called a frustum.

What does Hollow Cone create?

It creates a conical tube open through both ends, useful for reducers, adapters, covers and sleeves.

How is the funnel outlet calculated?

The outlet outer diameter equals the inner diameter plus twice the wall thickness. The cone and outlet tube form one continuous model.

How should the model be printed?

The lower end is placed on the print bed. Some funnel proportions may require supports depending on the wall angle.
