Adapter to connect a removable 150mm flexible duck to a 250mm Ceiling Extractor to remove Solder / Flux fume.
designed to be printed on a CR-10S PRO , so a 300X300 bed size
because of the size of the BaseCoverRetainer , i had to break it into 2 to fit on the bed, then glue those to the Base directly.
also design WallRetainer to hold the Base directly, since i was not sure if the superglue would be strong enough. Can't be too careful...
using 4 X Wall Retainer, but you can also not use them, or use more of them...
wing 4G 9mm Sheet Metal screws to the airflow plastic Grille
Ceiling can is a Clipsal AirFlow CE250

initially designed to have a 5 - 6 mm Rubber EPDM Sponge to improve the seal, but the seal was very good as is, so i did not put any rubber seal between the base and 150mm adapter. using the Hook-1.5mm
make sure the Hook are laid flat on the bed to increase strength.
Hook are using M3 X 10mm screws. Base already have pre threaded M3 holes
