Another PLA filament I use prints this thread without any problem but this metallic filament seems to keep extruding when travelling? Or that’s my guess at least. It looks like more than an ooze. I tried increasing the retraction length but it didn’t change anything. Does anyone have an idea why it is printing like this? Here is the file for orcaslicer if anyone is interested:

The thread has too much of an overhang for your layer height so the outside wall layer has nothing to adhere to when printed. This “carries/bridges” the extruded outer wall filament to where the thread overhang is less and this is why you see this pattern. Printing at a much lower layer height will help with this. Also adding a fillet to the thread crest will help as this pulls the amount of overhang in towards the root where you have support while maintaining your major diameter.
Thank you very much! Actually now I remember that the last time I printed it with the other PLA filament I used a 0.8 nozzle and both the layer height and width were twice as big so there was less of an overhang.
