Here's the carnage! Was running a long print and saw this when I went to check on it. Was running the stock Ender 3 hotend with a Capricorn tube fix for nearly 5 years. Served me well. I haven't yet been able to remove the white PLA. To see the full damage but, I'm pretty sure that the threads are gone.
Guess it's time to upgrade the hotend.
