My uncle recently gave me his old 3d printer, an Anycubic I3 Mega, because he wasn't using it, and I've been meaning to get into 3d printing. He hasn't given it any maintenance since he bought it, and barely used it, but the nozzle's clogged and it's not printing properly, giving a weird gaps/lack of material as if it was underextruding, internal structures of the prints not coming out properly, sometimes just moving the nozzle without anything coming out.

Based on my testing, it's a clogged nozzle, so I need to get a new one. Does it use a standard nozzle, that I can buy anywhere, or do I need to buy a specific type of nozzle?

Basically beginner here, go easy on me.
