This 3D design is a filament sensor mount specifically made for Ender 3 V2 printers. It features a dedicated slot for a micro switch and a channel for the filament to pass through. When filament is present, it presses the switch; when the filament runs out or breaks, the switch opens. This mechanism is ideal for detecting filament runout or issues during printing.

The design is easy to print and optimized to fit seamlessly with your printer. It can be quickly assembled with a micro switch and the required wiring.
