Description
This is a custom-designed servo horn made specifically for the MG90S micro servo.
It’s intended for projects that require 2 mm-diameter connections, such as lightweight linkages, control arms, or small mechanical assemblies.
Although I use it on my own RC plane, I'd advise against using it unless you can afford losing/crashing your model. Printed in PETG for a little flex but ABS/ASA should work fine as well.
This part has been dimensioned based on the MG90S servo spline and 2 mm mounting features.
Fit may vary slightly depending on printer tolerances—adjust scaling if needed.
Use at your own risk.
