what could have caused this shift?
Also I am printing in PETG and often I get the part curling up off the bottom and ruining the geometry.
Is there anything I can do to reduce the curl and peel of prints?
Increase fan?
Kill fan?
print in enclosure?
Change part geometry?
thanks!

Re: what could have caused this shift?
Easy.
Your design has very long slat pieces. This is not an issue unless you print them upright like yours are oriented. Those long parts are just shaking all over while printing.
You can notice how the print quality on slats gets worse the taller they got. I think you are lucky that it was only off a bit and did not cause a major failure from bumping the printhead.
The fix would be to add some small tabs between the slats so they are supporting each other at a couple of spots.
Also, no fan for PETG. High bed temp. No air fan/vent blowing directly on the print bed.

I'm finally back to where I started two days ago!

Re: what could have caused this shift?
Thanks, I agree with you but the damage was only in one very specific area, maybe the print caught on the nozzle.
No fan at all? Don’t you need it for bridging?
