Geared Filament Guide

When working on several objects I saw some z-line breaks in my work. After stabilizing the frame they were sometimes still there. My roll of filament is on bearings, filament is guided through a hole and guess what, sometimes things are just not running smooth. So I decided to remove this part of resistance and designed a dual-bearing filament guide.
The horizontal bearing is a tight fit in the static part, as well as for the rotor. Mind you, this is just a quick solution and I have no intention to refine or upgrade - it works.
