Optical Filament Runout Sensor V1

The spring I utilized has a moderate level of tension, precisely sufficient to gently elevate the Optical Interrupter when the filament is disengaged, thereby preventing any potential issues with filament entanglement. Spring Dimensions: Wide - 4.30mm, Length - 15.00 mm To ensure optimal performance, print the Optical Interrupter at 100% infill in black, and use a minimum of 25% infill for all other parts.
