Finally, a ball with two holes.
Placed a sphere around one hole of the parabolic cyclide, to remove the handle, and with another sphere, did some trimming, fillet, rotate copy, etc.

Two edges fillet well. Their fillet faces were copied to fillet surfaces, rotated twice to the other hole entrance, and used
to trim the other two edges which previously did not fillet with the Fillet command.
