I'm trying to use a screw function to create a spiraling object with an axis that changes over distance. In the attached photo I have a screw with a uniform axis, but I would like the spiral of the screw to follow the geometry of the "egg," so the screw has a small axis at the bottom/top of the egg, and widest axis in the center of the egg. The egg is a UV sphere that has been scaled in the Z axis by 1.5x. I appreciate any recommendations for how to approach this!

Add Sphere and add Spherical Spiral (you have to enable addon Extra Curve for that).
Parent Spiral to Sphere.
In Object mode scale Sphere to egg shape.
Rotate Spiral.
