Sheet Metal Elbow Free 3D model

Occasionally I generate some flat patterns for the fab shop guys to make elbows with. They make a 90 degree in 5 parts, with the seams opposite of eachother. With this model I can just edit the radius and diameter in the sketches for the application needed, and generate a new flat pattern. For a 45 degree, I'll just extrude cut halfway though the center piece.Enjoy.
