@Gerrit @hotellonely you guys rock! I soaked it in acetone overnight, took it out this morning and started pushing the nozzle needle into it. After I got the needle stuck in, because the ABS on the tip was so soft now, I waited for the acetone to evaporate, and then hit it with a mini torch for about 10 seconds. Finally I was able to push the needle all the way up almost to the top of the block, removed it, heated it with a torch again, and then stuck an Allen key in top, and pushed down hard (obviously holding this thing with needle nose pliers), suddenly a ton of filament squirted out of the tip in a perfect 0.4mm stream (about 10 inches long). Stuck the print head back in and fed some PETG into it, it worked. Now I’m doing a cold pull to remove any remnants. You guys saved a print head for me. I owe you both a pint of ale. thank you!
This is what the cold pull looked like:
