black hole spacetime model 3d

I want to create a grid model for the spacetime curvature of a black hole. I only have one color of filament, so make the black hole at the bottom of the curvature look like a black hole with its accretion disk. Make the curvature more severe but not realstically high because I want it to fit in my 3D printer. Also, at the bottom of the curvature like in the image I provided you, put the balckhole. I do want you to also have the model cut in half like in the imaage to see the blackhole and curvature nfrom an inside perspective. And make the black hole more spherical with a disk around it, and make it size-appropriate to the size of the curvature around it. Make the spacetime (grid) actual grid lines that curve around the black hole, rather than a spider web. Simply put, make it like the model on the left in the image, but make it not as long and make the black hole more distinguishable.
