This is pretty similar to the Red Oak design, although I made it from scratch.

This is pretty similar to the Red Oak design, although I made it from scratch. This one was created in FreeCAD 0.19, though.
The model basically consists of two spline loops for the top and bottom faces of the boomerang ("periodic splines", as FreeCAD calls them), and then a loft between those. If you want to play with the shape, just drag around some of the spline points.
FreeCAD is a little more stubborn than commercial CAD software, but then it's free as in "freedom" as well as free as in "free beer".

Notes:
Use lots of perimeters, top and bottom layers for printing boomerangs. I usually go with 6 at .2 mm layer height.
