Guidler for a Gregs Wade.

thingiverse

My filament pusher was enhanced by Tom's update (http://www.thingiverse.com/thing:16928). I incorporated a filament guide on the idler, which I termed as guidler. Additionally, I applied his modifications to prevent the front bearing from rubbing and included a printed spacer for avoiding rubbing of the bottom bearing. The opening was widened for improved access to the hobbing, another suggestion by Tom. Furthermore, I adopted Triffid Hunter's advice to modify the hinge support piece for easier removal. Many thanks to Tom and Triffid for their valuable ideas.
