Combination Filament Guide and Sensor

Update, Jan 29, 2019: No one has complained, but I just realized that I never included the bearing spacer and ring that goes with this from robathome's original design. Now everything is here in one place.

I love this Filament guide by robathome, and thought that this would be perfect to hold my remixed filament sensor. I've merged the two together while extending the arms on the Filament guide to allow for the extra clearance needed for the sensor( actually microswitch) housing. The roller ensures a smooth transition into the sensor housing, and the sensor in turn serves to also keep the filament away from the Z screw.

Note that while the filament path is sized for 1.75 filament, I actually drilled it out so that a piece of 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.
