Heard about the holes in walls, but have no experienced it for myself, this print is pretty awful !

@Crankshaft Happy New Year! Wow, that’s not good. Are those the stock settings? Did you try increasing the infill/overlap area in the strength settings?
I actually printed the poop chute door extension recently and was able to print on the thin edge. I was skeptical but it actually worked.
