I recreated a cabinet/drawer knob (Liberty's "Garrett" or “Classic Round” - they are both the same thing). It was a journey. I included a FreeCAD file and additional versions (largely untested) so it can be used/edited for use with with different standard screw sizes (Metric/Imperial) for convenience/versatility. No supports required.
