F physical filament sensor

A Physical Breakage Sensor Please use Google Translate, my English is not good and I'm worried that it may cause misdirection. A device to indicate physical breakage Note: This is only a warning, when you see the breakage, you will inevitably exclaim an F-word in your heart. So now your printer displays this word for you, please suppress your anger and come slowly. There are two states: When there's filament, it's a horizontal thumbs up; when there's breakage, the hand rotates and points up with the middle finger. So when you see your printer pointing at you with its middle finger, fix it. It's best to use <=0.2 layer height because of the holes and details. In addition to the printed parts, you'll also need a rubber band, a thin iron wire, an M3 screw, an M5 screw, and patience. There are a few places that need modification, but everyone has STLs, so I'll post them first and update later. Because the rubber band ages, the demonstration is not very successful. Later, improving it with a new rubber band should work smoothly. https://youtu.be/_zW3q4mSojc
