Moving to the face plate and the mount for the actuator arm.
Here are the parts.
For the face plate, I raised the center gray part, the wires, and the connectors. For the mounting post for the arm, I raised the collar and cut the holes out. As for the "stabilizer" arm. I made the thinner part of the arm a bit thicker and made the top connector piece a bit thicker.
The face plate is in place, the stabilizer arm is attached and the mounting post for the arm is in place.
