After stripping a couple of the micro servo horns provided on a Freenove Hexapod kit I found no one has printed the horns for these tiny Emax ES08AII Servos.
These don't have teeth due to the limitations of my 0.4 nozzle so used a small drill bit to adjust the hole for a nice firm fit on the servo. Printed direct on heated bed at 100% Step and Freecad files included for modification.
