Create custom servo horns – chose the number of arms, the length of the arm, the number of holes and more.
The given values for the servo spline are for Futuba 3F splines. They will fit onto any Futuba 3F compatible servo. If you need horns for different servos, you can adjust the servo spline parameters accordingly.
Print the servo horns sideways on the print bed to increase resolution of the teeth. The examples are printed in PLA with 100% infill, 0.08mm layer height and a 4mm nozzle on an X1C.
Spline values:

Spline Screw Diameter | 2.5 |
Shoe Height | 4 |
Tooth Count | 25 |
Tooth Depth | 0.3 |
Tooth Base Width | 0.7 |
Tooth Tip Width | 0.1 |
Updates
2024-11-13: Added STL files for more standard sizes and a 3MF file combining them all for an easy print. Just select the plate with the right number of arms, and skip any horns you don't want to have printed.
