- rods should be roughly the same length (+/- 2mm)
- rod-ends should be aligned
Time for some hot-glue.

Push the rod in all the way...
Add a little more hot-glue around the base / rod to make it extra secure.
A couple things here.
Time to attach one end of the armature to a servo; start by cutting off one end of a servo horn.
Hot-glue the servo horn to the servo horn extension.
Screw the armature on...
And add an M3 nut to hold everything together.
