About this 3D model

This should fit a 2 inch (50.8mm) hole and give you a nice louvered cover. I recommend rotating and printing with louver side down. If you need a different size, please scale accordingly. Update: This fit perfectly in a hole, that I cut, with a 2 inch hole saw mounted in a drill. V1 - louvered circle grill V2 - louvered circle grill with 1 central support running down the center of the louvers V2 - louvered circle grill with 2 supports running down the louvers for extra stability.
