Well, I think I've run out of ideas to get filament out of the hot end of a old 3D printer I have..... worse correct hot end cost more then the printer did when it was new. I might just try a different hot end, but it would be really nice to find one that at least has the mounting holes in the right place.
I am really thinking the printer has just become parts.
Maybe I can take a very small drill bit, and try to drill out the filament.
