I'd use a rigid thread repair, like TimeSert, over Helicoil because of
the plastic. Another option is to use epoxy thread repair. You coat
the screw with a release agent and then epoxy. P{ut the epoxy coated
screw in all the way without the handle. Auto stores sell kits or use
cooking spray for the release agent and JB Weld. Worse case, you have
to go back and drill it out and add a TimeSert.
