Fan silencer

I can get no fan that won't emit tons of vibration in rotation.
It make noise, and it add "ghosting" artifact on printed surfaces.

So I'm trying to detach fan from printerd head with an antivibration support.

One is just between fan and support, fixed with screws added of "little cap" as see in https://www.thingiverse.com/thing:3036948

Other is more complex one. Should work as a damper, totally separating both fan and support introducing antivibration material.

I shouldn't have turn
