Exhaust Vent Flap replacement

Looking for Covid Lockdown home improvement projects, my buddy Geoff made something like this for his home, and that reminded me that I could stand to do the same.

Local hardware stores did NOT carry replacement flaps, and replacing the entire exhaust fixture would have made it into a much bigger project.

Petg seems like an ideal material - and modelling the replacement was a snap - there's not much to it other than matching the proper dimensions.

I doubt many of you will be able make use of this particular STL unless you happen to have the exact same fixture, but hopefully you might be inspired like I was to take it on as a simple and satisfyling little modelling/repair project!

(This particular flap is 19cm x 5cm with pins that extend to 20.5cm if it DOES help you out)
