Filament sensor switch specific to da Vinci 1.0 series printers

This is an over designed "out of filament sensor alarm". I wanted this to be totally self contained including power source and alarm buzzer. The design is a take off or remix of several other similar designs. But, I've built in the battery and attached the buzzer. The problem is where to attached the sensor on the da Vinci 1.0 series without restricting free flow of filament. I designed a inner and outer clip to align the filament and guide it to the sensor. I only have a single extruder, so I used the 2nd guide hole for the clips. If you use both extruders you'll need to remove one or both of the guides. The actual sensor is velcro'd to the underside of the frame. power source is 2025 button battery. The unit consist of 4 parts...the case, cover inner clip and outer clip. Buzzer is glued to bottom of case.
