A simple filament guide with integrated micro swich as filament runout sensor.
It is directly mounted on E-axis with the upper two M4 screws of X-axis bearing bushing.
As the endstop swich has very small roller, I used grooved pulley (13 mm outer diameter, 2 mm groove) as interface part.
V1.1 - adjusted filament path shape, so the filament wouldn´t stuck during filament unload; enlarged holes for screws; other design optimisations to reduce weight and look less bulky
Thanks to precise dimensions of the filemant guide from Cyberlamb, that I used so far, it was easy to find correct location of filament line to extruder.https://www.thingiverse.com/thing:2357589
