Optical filament runout sensor - Work with all the filaments!
thingiverse
Simple yet effective solution for all 1.75mm diameter filaments using an optical endstop and gravity's pull. This system works seamlessly with transparent filaments too, thanks to a clever fall mechanism that defies Newton's laws. To get started, simply insert the filament without the knob in place, then position it so it rests on top of the filament. As the filament exits, the knob will drop due to gravity, triggering the optical endstop. The two mounting holes are designed for profile 2020, but keep in mind that this setup relies heavily on proper leveling.
