Fume Exhaust Adapters for Garden Hose

I didn't want to cut into the printer to exhaust the fumes, so I figured that since the pipes that the filament spools are on are hollow and threaded, I'd use them.
Firstly, I designed a cap to cut off airflow through the right pipe since I'm not using it. Next, I made an adapter that would allow me to use a garden hose to connect to the outside threads of the other pipe and keep the filament spool in place.
Then I created another adapter to hold my fan (1.59") in place over the exhaust pipe
