The "Ender 3 Filament Roller Guide" works fine on my CR10-S but I can not use the filament sensor.
So I create this remix. It was designed very fast but works fine with the original filament sensor delivered with the CR10-S. Maybe it is a bit too tall in the X axis - maybe its perfect. Feel free to design a better one. Print it in the current orientation and there is no need for support.
I like to keep both (roller guide and sensor) in single parts so I can replace/remove each one screw-less. To replace the filament you can simple unmount both but it is not really necessary.
If you dont want use the filament sensor, the "Ender 3 Filament Roller Guide" is the better choice.
This is only the holder. All other parts you need see the "Ender 3 Filament Roller Guide".
Made in PLA. I do not use a screw for the roller. I just print a bolt in PLA, 3.3x16mm created in tinkercad. 100% infill and glue it in.
As top spool holder I use this: https://www.thingiverse.com/thing:3051210
Prevent the filament sensor to move during the print? Thanks to RandoMax (see comments here and his make: https://www.thingiverse.com/make:725864 ) he found the solution: https://www.thingiverse.com/thing:2897667
