Circular Vent Cover (small for RVs)

thingiverse

I made this little vent cover for my vintage fiberglass trailer. All of the furniture has these vent holes (1 inch big) and the old molded plastic covers were brittle and some had broken over the years. (original is white in the picture). The black is shown installed. I recommend PETG or other high heat filament as campers usually see the full heat of summer. When installing the vent cover be careful to not push on the fins.
