I've been trying to print this: https://makerworld.com/en/models/180646-underground-corner-tunnel-for-aquarium-fish-tank?from=search#profileId-1012676
With petg is consistently fails when in finishes the overhang and the two pieces of the part finally connect on the same layer. I haven't messed with settings at all since I'm not even sure what the problem is between the nozzle hitting the part, warping during print, use of supports, etc.
