I do not know why difference() does not work for me.
As MichelatOZ pointed out, somehow my eye did not catch the”;” after the
closing brace of the resize.
Yes, the form is something like that you nophead provided, and difference()
is working as it should. I made a little modification to the module, now it
looks like this:
// Module of the airdirector
module airdirector(){
translate([-2.3,0,0])
rotate([0,90,0])
rotate_extrude(convexity=10)
translate([aidelpsl/2-1.8,0,0])
rotate(45)
resize([aidelpsl/3,aidelpss/3])
difference(){
circle(r=(aidelpsl-aidelpss));
circle(r=(aidelpsl-aidelpss-10*aidthick));
}
}
Thanks, again,

Also note that you need convexity= in render().
If you try this (to see inside) without it you will see why.
difference() {
union() {
// Draw the airdirectors
color("Teal",0.5)
render(convexity=10)
translate([pairdirector1,0,0])
airdirector();
//color("Teal",0.5)
render(convexity=10)
translate([pairdirector2,0,0])
mirror([1,0,0])
airdirector();
}
cube(40);
}

Suggestion: use #cube so you'll see where it is.
