6in Corrective Cornhole Flange

For those of us who decided to make corn hole boards during quarantine but didn't have a 6" hole saw. If you, like me, have an unsteady hand and your jigsaw skills left you with an uneven hole in your board, this flange will correct it. Simply glue to the underside of the board with construction adhesive or comparable glue. Fill in the remaining gap with wood putty or joint compound and sand down to desired smoothness.

This was my first-ever design. Although it was derived from a cylinder in TinkerCad, when it was enlarged it came out angular. If anyone wanted to remix this to make the hole truly round, that would be great!
