Combination Filament Guide and Sensor

thingiverse

Update, Jan 29, 2019: I'm adding a bearing spacer and ring to robathome's original design that was left out earlier. Everything is now in one convenient place. I love robathome's Filament guide and thought it would be perfect for my remixed filament sensor. I merged the two together while extending the arms on the Filament guide to allow for extra clearance needed for the sensor housing. The roller ensures a smooth transition into the sensor housing, and the sensor keeps the filament away from the Z screw. Note that while the filament path is sized for 1.75mm filament, I actually drilled it out so that Capricorn tubing would press-fit inside, and then carved out a section of the tubing where the microswitch roller is. It works great with no chance of wearing on the filament or causing drag. Sorry for the poor quality photo, my phone camera isn't working properly at the moment.
