Rectangular to Circular Adapter Creator (Parametric)

I started this project because I needed the dust collector adapter model included in this post. If you're interested in that model only, you can go here for greater detail. However, as I designed the adapter in Fusion 360, I realized I could generate a fully parametric model that would let others customize their own rectangular to circular adapters for dust collection, HVAC, vent lines, etc. The Parametric Model: I have included both the Fusion 360 .f3d file and general .step file to use in whatever CAD program you might like. The model has User Parameters defined that enable changes to the following:Rectangular end length, width and heightRectangular end taper (inward or outward)Circular end diameter and lengthCircular end taper (inward or outward)Distance between the circular and rectangular fittingsX and Y offset between the circular and rectangular fitting endsWall thicknessThe dimensioning is set up to be inputted as inside dimensions for the ends, but if outside dimensions are th
