I don't quite understand, are you saying the tread prints ok but is not strong enough or that you are having issues printing the thread because its not as stable? I have only printed it out of PLA and its strong enough to clap things but I would think if I tightened it really hard it's going to break. I would think printing it out of PETG would make it even stronger.
