Extruder Idler with replaceable guider

SummaryThis is an extruder idler/guider for a Greg's/Wade's extruder with a replaceable filament guider. I always have issues where the guider wears out after many hours of printing and i have to replace the entire idler. This idler has a removable guider, so that it will be the only thing needing to be replaced when it wears out. You could also print the guider out of Nylon so it lasts longer. The guider slides into the slot and is secured with an appropriate sized wood screw as shown in the picture above.Print SettingsPrinter: MendelMax 1.5Rafts: NoSupports: NoResolution: .2Infill: 40%Notes: I used ABS for both the idler and the guider in the example above. Also Shown with Nylon Guider.
