FilaSense - Filament Runout Sensor

thingiverse

FilaSense is a cutting-edge, user-friendly and versatile filament runout sensor that offers effortless printing, use and mounting capabilities. It employs a microswitch for reliable filament detection and can be seamlessly integrated into 2020 or 2040 extrusions, or any other frame utilizing the two M5 holes. FilaSense comes as a single file to print, making it a small, swift and cost-effective option with minimal material requirements. You can easily access the CAD files on Onshape.com: https://cad.onshape.com/documents/4b417211dd7396fa56bbb31f/w/b560786274fd9e0060663aa1/e/ab1b26a230356296ade5d2a5 Here is a breakdown of the required components for FilaSense: * 1 x Printed part * 1 x Horizontal Endstop (available at https://www.aliexpress.com/item/LERDGE-3D-Printer-Parts-Mechanical-Endstop-Limit-Switch-Module-Endstop-Switch-Horizontal-Type-For-Reprap-Ramps1/32816845922.html) * 2 x M3x8 to secure the endstop * 1 or 2 x Screws for mounting the sensor (I used 2 x M5x10 screws to mount it on my 2040 aluminum frame) **Update:** A revised version of FilaSense, dubbed FilaSense_v2, has been uploaded with slight modifications aimed at simplifying filament insertion.
