I cut the drivers (not the company) slack for some of this sort of stuff. I had a friends dad that delivered for UPS apparently the expectations are impossible. You don’t leave till deliveries are done but it’s not possible to do in a normal day. Marking things delivered that weren’t was apparently the only way to see his family sometimes.








That’s a tough one. Those small points hanging ledges pose a lot of problems for printers and petg is not a forgiving filament type.
As others have said, petg can be a harder filament to print. Even dry it tends to be more viscous leading to oozing, stringing. I’m not convinced that’s the problem but it could be part of it as build up from stinging or over extrusion can cause collisions leading to something like this.
The damage looks like it’s happening on one side. That hints at either a cooling problem or some movement or seam placement problem.
Looking at pictures of your printer it looks like it has too fans so I suspect that side had direct cooling and the openness means it’s probably not getting a wall that would affect it.
Related to movement, speed/acceleration could be an issue. You might have heard scratching while printing in this area. If so slight warping during cooling or from over extrusion could lead the nuzzle colliding. On a more solid print you could probably get away with ignoring it as it wouldn’t affect the print but with such small parts small impacts over time will lead to knocking parts off or distorting them. Try slowing down the print. Most of the print here is delecate but you can do that in modifiers if you want other parts of the print to be fast.
Not sure how much that adds or helps but good luck.
