About this 3D model

-Replacement for the standard RV vent fan blade. -Be careful, this could be dangerous in application and cause personal injury. I recommend covering with a screen to prevent injury. 9/29/13 UPDATE: Had a chance to install. I would recommend making the shaft hole .005 in. smaller. I used ABS glue and I feel it is secure. I would say this fan blade works better than OEM.
