Cessna 172 Air Vent Silencer Control Knob – 3D resin printed replica

3D resin printed replica of the Cessna 172 Air Vent Silencer Control Knob (S1390N5). It mounts on the cabin fresh air silencer boxes. (0710013-4, 0710013-5) I have refined the original knob to be more aesthetically pleasing then the original Cessna design. This listing includes control knob (color matched to Cessna 172 interior) and a spring. If you have a owner maintenance certified aircraft this piece will fit just like the original.
