im surprised the PLA worked for a few months, should never be used for such things (part of that learning tho 😉 )
hotend parts made out of PLA is like internet explorer on a new computer. you only use it once, long enough to get something better.
great you got a handle on ABS, it's all i print these days, and is definitely the way to go,
but if you're ever in a pinch and can't get ABS for printing parts, PETG > PLA
