filament guide cr10s pro

filament guide to stop shaving of filament into runout sensor , designed to use the 608 bearing .

I have supplied a printed wheel if you don't have a 608 bearing labeled nb3

press fit the bearing race " stl br3 " over the 608 bearing

press bearing with bearing race into main body " stl filb150 "

slide body from the back to lined up position over runout sensor

pla works fine here , no supports required

this is the new and improved design , better feed angel of main body arm
