Inline fan 10 inch to 6 inch adapter

I wanted to connect an AC Infinity 10 inch inline fan to my exhaust system, but didn't want to add 10 in hoses. I created this adapter to connect the 10 inch fan to a 6 inch exhaust hose. This model SHOULD be a compression fit on the fan side itself. The hose side does have threads that allow it to "screw in" to a typical 6 inch exhaust hose, but I do still recommend using some kind of clamp on the hose side. PLA should be fine, but you probably want to go with something like PETG instead.
