Ender 3 Vent Ring - Inward facing airflow

~~Replacement fan nozzle for ender 3. focuses air toward nozzle rather than at bed. works with stock fans and screws.~~

~~I have very little experience with modeling, im sure someone better than me can remix it and improve it even more. overhangs can get a little spaghetti-ish. nozzles could probably be extended towards the center and made more narrow for a more focused airflow. might need some sanding to increase gaps between nozzle and print~~
