Ender Filament Runout Sensor

thingiverse

I installed BLTouch on both my Ender 5 and Ender 3, rendering the z-axis limit switch obsolete. This is a basic container for that switch to enable it as a filament runout sensor if your mainboard allows this feature. I'm working on mounted versions for both machines, but for those looking to attach this to another mounting mechanism using glue or tape, I'm sharing this design. It works mechanically and triggers the switch consistently in my tests.
