Mmmm PETG failures, my favorite subject here.
let me guess. P1 with regular stainless steel nozzzle 0.4mm? If so, my biggest suggestion would be to upgrade to at least hardened steel, or better yet e3d obXidian one.
The reason is that PETG tends to stick to the nozzle and travel along knocking everything on its way. Also, your overlapping infill doesn’t help here.
