Inspired by @OZL01_403523's runout Sensor Solution, if you need a faster solution with less Hardware, check out https://www.printables.com/model/298272-ender-3v2-filament-runout-sensor .
While browsing, I saw Oslo's option to use an old Z-axis sensor as a runout sensor. I thought about how abrasive filament can be and how thin the metal part of the sensor is. I wanted to design a solution that would be less abrasive on the material.
Another popular [or rather necessary] update to the Ender 3V2 is the metal extruder upgrade. This also frees up another ball bearing for the filament guide.
This is used in this project.
For my solution, you need the Z-axis sensor, which becomes obsolete after a CR touch uprade. You will also need the aforementioned ball bearing.
Necessary Parts
1x Z-axis sensor
2x Z-axis sensor screws
1x extruder ball bearing
5 x M4 threaded inserts
5 x M4x10 Allen screws
Some threadlock
Aditional Parts
1x Bowden tube clamp
1x Short piece of Bowden tube
Don't tighten 1, let the cantilever enough space to swivel. Put some threadlocker on 1 and 2, 2 tighten.
Bend the Sensor Switch to make it as sensitive as you need it.
