Longer Sturdy Filament Guide

Remixed from http://www.thingiverse.com/thing:1728482. In most respects it's about the same, but the guide is a little further away from the frame (the same distance away as https://www.thingiverse.com/thing:979847 which was the original design).

As with the originals, will work with both the original filament holder and https://www.thingiverse.com/thing:1635585 and can also be used with the filament locker here https://www.thingiverse.com/thing:1280498.

All those versions work, this change is just personal preference.
