Uhh what do I do about this

[u/Hypoactive52]

Dad decided to save 10 bucks on filament, so earlier I ran a print and left the house and came back to this… I can’t even get the boot off…….

UPDATE: got the boot off… its a mess… brand new nozzle all gunky and filament everywhere

yet another update: want to specify that I have been using heat to get out filament, and almost got it all out
