You could use a CSG of three tori and two cylinders.  Basically you do what
you do now, but then you create an inset with two of the tori and the
cylinder.  I don't have time to create a scene, but this ASCII art should
explain it a bit better, I hope:


    ****oo ------- oo****
  *****oooo ----- oooo*****
 ******oooo ----- oooo******
 *******oo$ ----- $oo*******
********$$$ ----- $$$********
********$$$ ----- $$$********
********$$$ ----- $$$********
 *******oo$ ----- $oo*******
 ******oooo ----- oooo******
  *****oooo ----- oooo*****
    ****oo ------- oo****

* = the outer torus, with the part already cut away with one cylinder
o = the two inner tori
$ = the inner cylinder (needs to be open and/or inverted)
