Hah! I had to do a double take there and go back to the "3D Printed Aircraft Parts" group I'm in on Facebook, because that yoke horn kinda looks 3D printed. The one I just saw a few days ago there is different, though.
What are your buttons? Your horn is a lot like mine, and my left index finger button is my PTC for the GTX 350c, with the PTT under the index finger when not extended.
