About this 3D model
This is a decorative flange for cut holes. It is a customizable version of my bean bag toss flange, http://www.thingiverse.com/thing:107363 The inside diameter, the flange lip and the height are adjustable variables. You will find a sketch with dimension definitions. I use a Replicator2 with a bed width of 6 inches (150 mm). This sets my maximum values.
