Looks cool. Is this made from progressivly larger, fatter tori and cylinders, or is there a better way

Not really.  One have to combine different csg operations... But this
time,  I did it more cleverly,  cause I put everything of this csg profile
into a macro,  which one allow me to use the same profile with
different radius...  But it would be much better to have a macro
allowing to change the shape of the profile too !!
