don't know if this is what you needed, I once tried to DIY a dust deputy cyclone that is basically a larger cone and there was a program that calculates and prints the shapes for you. then pasted to the sheet metal and cut then roll it into exact shape. Tried that on paper and it works never find the metal to finish.
for yours would be ...
Diameter A = 1.5 inches
diameter B = 0
Hight = 2 inches from your spec then print ...
