Potato Gun Shells 1.5" and 2"

Fin stabilized Shells for a potato gun, sized for 1.5 and 2" PVC, both schedule 80 and 40.
The flight distance can probably be improved just slightly by scaling only the height of the 1.5" shell to about 90mm and the 2" shell to around 110mm, I haven't tested this, I'm only going off of the shape of the teardrop, these already fly extremely far as is and can be reused several times.
