Filament Sensor JG Aurora A5 for Bondtech Extrusor

thingiverse

Filament Sensor for Use with Bondtech BMG Extruder. Designed to Work Seamlessly with the Original Switch of the JG Aurora A5, its Screws and Metallic Sphere of 6mm. The switch is activated through a metal ball inside the filament tube. When the filament is in place, the ball shifts to activate the switch, while the filament runs out, the ball moves away from the switch, placing it in an open state, and the printer detects the end of the filament, stopping the print. Made with 0.1mm layers to minimize friction between the sensor and the filament inside, I only used supports for the reduced ring areas that hold the piece together. The rest of the design relies on its own structural integrity without supports. I've attached simplified 3D factory files for easy opening with my configuration. If you'd like to make any adjustments, you can download the Fusion360 file and work with the original design. Enjoy!
