This large container is made from 2 Loft surfaces. The outside surface uses 10 vertically stacked star-like curves as controls for generating the Loft surface. The inside uses the same approach except the control curves are simple circles. Here is a short video that gives a better view of the container's detail: https://youtu.be/CBe29ig8Edw.
