Drybox Right Angle Filament Guide

I printed the parts for two Dry Boxes from Thingiverse item http://www.thingiverse.com/thing:1999478. I wanted to stack the two Dry Boxes and put 8 rolls in each box, so I mounted the grommets on the end of the box.

However, the printer was on a table above the drybox, and there was too much friction when my printer was pulling the filament 90 degrees to the filament grommets, so I built this guide to hold a bearing to make the transition with very little friction.
