SG90 9g Micro Servo horns' set

Complete set of SG90 9g micro servo horns.
Tired of losing or breaking them, I drew the horns with Freecad so that I have many spare parts for my robotics projects.
The set includes the original equipment of the servo, in configuration with holes (for model aircraft) and without holes (for robotics).
The dimensions are compatible with the originals.
The dimension of the inner hole (graft hole) is precise and the connection on the rotating pin of the servomotor is done by pressure and it is advisable to insert the locking screw.
I recommend:
100% of infill,
0.10 of layer,
30 mm/s of speed printing,
a little support under the graft hole.
Good fun ... ;-)
