Truncated cone

A cone, optionally with the top cut off. (In that case, it’s called a frustum). Can be used to help create the geometry for a beaker, vase, party-hat or lamp shade. If you'd like a real cone, just use zero for the top-diameter. Tip: do not score or fold the fold line this template to keep seam smooth.
