A funny thing happened on the way to a working levitating top prototype: Modelling this in FreeCAD led me to the realization that the powerful Nd magnets I am using can be lined up with all poles in the same direction IF they are press-fit into the top structure.

So now that I have the moving part fully drawn (sans magnets), I also realized that I don't have to make the first article by machining. All I need to do is make a mold, which is sort of a 3D version of a photographic negative.
