Summary
A thing that serves two purpose!
It's a runout filament sensor and it's also a great filament guide with bearing!

Super easy to assemble. No fasteners!

Hardware needed:
608 bearing
Kw12-3 PCB Microswitch (https://ebay.us/Q7otPk)
I added the Fusion 360 file. Be warned though, I went through many iterations and it's a pretty ugly timeline! Good luck!!!

If you have an Ender 3 Pro, use this remix : https://www.thingiverse.com/thing:4563996

Check out this great video by Crosslink explaining how to install and connect the filament runout sensor to your Ender 3 and configure the firmware: https://youtu.be/5Jt-Qc67FDo

Just note, that it can be done connecting directly to your Ender 3 board or to the Raspberry Pi if you have OctoPi installed. Google it! :
