The complete cut-out body (minus impossible fillets)

Now all that remains is to apply draft to the planar side faces, using the same neutral plane as for the main body, and filleting. Apply a general fillet of 3mm to all edges. You will notice that there are several edges that cannot be filleted... this is a defect of the underlying geometric kernel which FreeCAD uses.
