Filament Guide

After trying a few other guides that did not fit the top of the Printrbot Simple Metal Z Axis, I decided to make my own. This guide is modeled to with the internal hole size needed plus a 0.4mm nozzle width. This allows it to fit snugly on the post. While I could have scaled up other's models to fit, I wanted to make one to prove my internal dimensions were printing accurately.

Plus the clip is open at the top that allows filament changing without having to thread the opening in the guide.
