Mark III helmet hinge problems

Hi guys,

I am currently working on my Iron Man Mark III helmet mechanism.

I am using the 3d printed hinge from http://www.therealtonystark.com.

The problem is, that the left arm (the one which is not connected to the servo) is too loose.
So when the visor is closing, it is not centered because the left arm is pulled down by the weight more than the right arm.

Do you have any ideas to solve that problem?


The ideas that came up my mind are:

- to glue the two arms in the middle of the connecting piece. They are just touching but not connected tight.
- to replace the hole where the left arm is attached with the frame by any type of metal piece (maybe a bearing) to make the rotation more stable
- to attach a metal rod between the two arms instead of gluing them
