Cône tronqué

A cone, optionally with the top cut off. (In that case, it’s called a frustum). Think of it as a beaker, bucket or a party-hat. The calculations are horrific, that's why I created a template for it. If you'd like a real cone, just use zero for the top-diameter. I added an extra line in the center of the template that can be used as a base line for curved text.
