Servo Horn Compatible with Futaba 3F or Hitec H25T

My hobby projects often find me needing a servo horn that I don't have. I wanted to model a horn with the correct splines to fit the standard size servos that I typically use. This Thing includes the model for a round servo horn with splines that are compatible with either Futaba 3F or Hitec H25T spline servos (this covers most newer standard size servos).

The horn is a tight fit and you may need to slightly scale the model to account for your printer's particularities.
