Bearing Holder with Pin Cutout - Remix

Thank you to starlos for creating an improved bearing holder design. I much prefer it over the traditional design since it stays in one piece much better. This remix does not alter the design at all but instead it slightly changes the dimensions. I made the gap for the bearing a bit larger to make the bearing sit a bit looser. I also extended the middle circle of the housing so that the only part of the bearing that touches the housing is the middle section. These changes result in consistent low friction filament pulling.
