Spring loaded servo saver

Spring loaded servo saver, connects a servo horn to a rod with springs so that if the movement is blocked, the impact goes to the springs, not the servo

Inspired by this setup here: https://www.youtube.com/watch?v=Ux5tgI1E0lQ

BOM:
metal rod, I used 1.6mm brass rods
2 stripped rows from an electical screw terminal block (picture attached)
2 springs from ballpoint pens (or similar)
A little bit of superglue

Assembly:

Attaching the end of the rod to the shoe:
At the end of the rod, bend a 90° angle on it (done so it can't slip out from being pulled back by the servo) and place the bent end in the servo-link-shoe and the straight part in the channel for it, make sure it fits, once that is done, take it out, put a little bit of glue in the channel and put the rod back in.

Attaching the servo to the servo-horn-extender
I tried 3d printing some custom servo horns, they didn't turn out well, so I just made an extender for it, place the original horn in the extender, line up the holes for
