biqu h2 titan 6015 part cooling radial fan duct

simple part cooling fan duct for the biqu h2. the titan 6015 radial fan is fairly quiet and moves a lot of air. its angled forward to account for the hot end fan exhaust and it also smoothens the airflow a bit. now i rather have problems with too much cooling than too little. Update 8.5.23: V2 hat circular nozzles for better aim of the airflow You need 3 ~20mm and 2 ~8mm m3 screws
