Gravity Well Education

Objects with mass distort Spacetime in a way that is refered to as a gravity well. Two objects attracting each other via gravity is a little like two bowling balls on a mattress rolling towards each other. I was listening to the WTFFF Podcast and I heard Tom Hazard talk about a 3d printed display of how gravity wells worked. I wanted to print it but I couldn't find it. Then I realized that I could just design what I thought it would be in blender using the two attached photos to scale the size of planets and the size of gravity wells.
The Center Rotation file shows the Sun's gravity well and Jupiter's Gravity Well. The Saturn's rotation file has a continuation of the Sun's gravity well and Saturn's Gravity well.
I was going to do all 8 planets with individual rotation cylinders but I quickly saw how my concept has a flaw because plastic is static in a way that gravity wells are not. Also I have not thought of a good way to depict eliptical orbits.
Would depicting just the Earth
