I’d assume it’s best to drill your holes before you anneal? Since the stiffer the part is the more likely it is to crack? Can’t find solid answer anywhere.

      The concern for moisture is overexaggerated. Without moisture it is too weak and will break. You want moisture. Pa6 is by far one of the weakest filaments when dry and is unsafe when dry. Any coating on the outside is very difficult to keep water tight when moving parts are involved and is more work trying to recoat it for no real benefit. If you live in the swamp, then use other filaments like 12, 612, ppa, etc but as someone who lives in a hot humid environment, pa6 is still good and stronger than pla. The lower rigidity when wet isn’t enough to cause issues. Higher rigidity is nice to have for some stuff and would be why I use the others.

        Okay thank you. I won’t even try to coat it then. Where I’m located it can be pretty humid. In the summer months the average is 75%~90%. In the winter months the average 70%~75%. What would you pick? Pa6cf20? Pa612cf15? Or PA6cf10?

          Brand matters not just the type of nylon and fill. You can try polymakers 612. I know their 12 is a bit expensive otherwise sunlus 12 is decent and cheap.
