Based loosely on ideas from juper42's control horns, but with smaller holes where the pushrods go through (for less slop) and an offset to allow the pushrod to be more centered over the hinge line for more even throws. These were designed to fit a mod I am working on for my Parkzone Radian.
I printed mine by rotating them so the long side was flat on the build platform. At that orientation, the base is angled at 45 degrees and should print without support. The bottom is just printed flat. They are small enough that I used 100% fill.
