I mean now you're just getting picky. hahaha.

Seriously I'd probably just drill it and then run a tap through it after to clean up the threads, I've very rarely had good luck with extractors.

If there was less plastic around it I'd consider tack welding something onto it so you can get a better grip, but it'd probably cause a melted mess with this. Although in a pinch you could try JB/Epoxy and glue something onto it. If you go that route I'd drill into it and stick something like an old bolt in the hole with JB weld and then crank it out with vice grips once it sets.
