Penny V3 Mech Mod | Help!!!

[Snapy1]

So the threadings on my Penny V3 have gotten screwed up, its like a copper connection and a plastic washer came up into the threads on the top of the mech mod. I try pushing it back as hard as I can with a screw driver it didnt move an inch, this happened whenever I took my rda off the mod.

Either unscrew the positive pin from the bottom (if it's threaded) or put it in the freezer and get it cold and try to pop out the pin and insulator. The insulator should be threaded, so you might be able to unscrew it once you get the positive pin out (which is binding it to the threads on the top cap)
