RV Vent Replacement Fan Blade
thingiverse
This RV vent fan blade serves as an alternative to the regular one; however, be cautious during installation to avoid accidents that may lead to injuries. It's safer to cover it with a screen for protection. In my experience on 9/29/13, I suggest making the shaft hole slightly smaller (by .005 in.) to ensure stability after using ABS glue for fixing. Overall, this fan blade performs better than the original one.
