I'm a newbie, It is my first big project. I read a lot about petg before starting. I ended up using the "bumblebee approach". Sunlu Petg filament, Bambu setting for Sunlu petg, print. I use Sunlu only because delivery with amazon in italy is very fast. Only "problem" very hard to remove supports inside holes for tpu gasket. If Benlevi read this: maybe using through holes all is easy and the structural resistance does not change. In any case, thanks Ben! great job!
