I needed some quick 1:24 figures, and these are the only full figure scans with open licenses I could find on thingiverse. I did some editing for clarity, printability and suitability for my purposes.
Each figure is approx 70mm high, which is 5'-6" in 1/2"=1'-0" scale. Scale as necessary for your use. All print fine without support.
Love 3D printing and geography!
