1kg spool of some tough-as-fucking-nails 15% glass-filled PET filament.
This is not your momma's PETG, this is some big boy POLYETHYLENE TEREPHTHALATE, a thirsty engineering material that won't make your front fall off (at least, not unless you really fucked something up). This shit prints just fine in open air, anneals without warping for those parts that just need that extra strength.
A hard nozzle is a hard requirement. Glass filled materials will eat right through your fancy plated copper in mere meters.
PEI with some sort of release agent
(see: goo.by.frank.af. Highly recommended, this may keep your bed from exploding)
