I was printing, and when my part for my model rocket was complete, I took it off the printer, removed supports, and it broke in my hand. Upon further inspection, it looks like my printer started printing off-center for like 15-20 layers, then went back to how it should have been printing (refer to picture). I will check the G-code if it happens again, but any help on other reasons it could have done that would be much appreciated. Thank you!
