Optical filament sensor with PTFE guiding

thingiverse

Raptorfx's simple optical filament runout sensor is a masterful creation.\r\nI chose to reimagine it by incorporating slots for PTFE tubes so it can be seamlessly integrated onto bondtech style extruders.\r\n\r\nFortunately, I won't have to use this myself since I discovered that the sensors I initially intended to employ are defective, but the revised design turned out well enough to share with others at least.
