Filament Runout Sensor - No nuts or bolts needed

thingiverse

No hardware, fast print, long throw filament out sensor. This switch housing and plunger are designed to be printed without supports quickly and not require anything more than the switch, some bowden tubing and maybe a little unused filament. There are 2 small zip tie slots and an m3 hole for mounting options. The filament does not rub on anything other than bowden tube to prevent wear or contamination and the throw of the switch is maximized to help prevent any false readings. This print does like a printer capable of doing an 18mm bridge fairly well.
