Filament run-out switch

thingiverse

Remix of "Filament run out sensor/switch" by RuanSerfontein was just what I needed. A few tweaks were made to the original STL, and a loop was added to the top for easy attachment of a string. This way, when the filament runs out, it won't fall into anything critical. To keep things tidy, a hanger was designed to attach to the top of my printer, making it simple to hang the string in place.
