Function-shaped hole?

frank_krar894

Wondering if there’s a way to draw a curve using a polynomial function. 

I’m making a 3D printed interactive manipulative tool for my AP Stats students and I need to create a hole in the shape of the Normal curve (AKA “bell curve”). 

It doesn’t have to be perfect, but it’d be nice if it I could get a decent approximation. 

Any tips other than using sketch tools and extruding the hole?

thanks

@frank_krar894, after using the above FS to generate a curve, you can then convert edges in a sketch and extrude the desired hole.
