Seems like parts which have small/tight threads like the one for the main lense dont print correctly with an 0.6 nozzle. Normally i dont have problems printing threads as long as i use a layer height of max 0.2mm but for the thread of the lense it doesnt seem to be enough. Better use a 0.4mm or smaller for printing lense threads.
Everything else seem to work with an 0.6mm nozzle using 0.2mm layer height. I used 0.3mm layer height for the base.
