Ender 3 Pro filament out switch and guide
thingiverse
This is my take on a filament out switch with guide. I modified the wheel and pin from https://www.thingiverse.com/thing:3061551. Redesigned the guide arm to work with the filament sensor bracket. This is the sensor I used: https://www.amazon.com/gp/product/B081W4KMHC/ref=ppx_yo_dt_b_asin_title_o06_s00?ie=UTF8&psc=1 This works well with OctoPrint and the enclosure plugin. You can add a rubber band or small screw to the end of the sensor arm to make sure it closes firmly when the filament is out.
