Parametric ConeTainers

Needed some containers for some cotton pads and q-tips. After making some simple cone based containers. I realized the simple set of parameters made interesting shapes. So ConeTainers is born. here it is as a customizer. try out some values. it's 3 diameters and the two heights between them.

Things need to be printed in spiral vase mode or with zero infill zero top layers to be containers.
