Ender 3 Pro Filament Sensor Mount

This is a simple mount for a filament runout sensor that fits the Ender 3 / Ender 3 Pro printers. See the image to determine whether it will fit the specific sensor design you have. The filament intake tube was designed so that it can accommodate a short PTFE tube if desired, to reduce the chance of filament-on-filament grind over time. I am using it without the additional tube, however, and it works just fine. Print in PLA or PETG for best results.
