The only motorization parts that you’ll need to scale are the faceplate helper arms. Match those to the scale of the helmet, ie if you’re printing the helmet at 96% then the helper arms will also need to be 96%
All the other motorization parts (servo mounts, faceplate lifting arms and faceplate mount will need to stay scaled at 100%. Depending on how small you scale the helmet you may need to move either the servo mount or the faceplate lifting arm mount a bit

i want to scale it to 95% but shouldnt the servo arm be different aswell then?

If you scale the servo arms they wont fit on the servo. Yoh have to leave them alone or you have to remodel them at the lower scale.
