About this 3D model

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. Of course all of this exhaust needs a place to vent out... so I came up with a design that fits through a .5" board and is screwed into place. A standard garden hose can then be attached. To keep rain from entering the hose, an exhaust hood was made. I put a grill into the exhaust hood to help prevent bugs and whatever from crawling inside (also provides support for the printing). I also placed a piece of screen material between the sections for a good measure of protection. I had to design a 90 degree adapter for my hose since the wall is too close to the back of my printer and would kink the hose. I made my own supports for the adapters and they can be simply removed with a twist of some pliers.
