Ender 3 Filament Roller Guide + filament sensor

I try to explain the best I can and sorry for my English :)

You will need to print:
1 - Top
1 - Box
1 - Coupling
1 - bracket
this is from the partner ((https://www.thingiverse.com/thing:3052488))
1 - ring OR ring-sm - print ring.stl first, if it isn't tight enough then ring-sm.stl is slightly smaller inside.
2 - spacers

Plus you will need:
1 - 608 bearing
1 - M4 x 16mm bolt
1 - We also need a filament sensor like this
