Cr-10 filament guide

filament guide for Cr-10 printer. I made this filament guide because i use a top spool holder (made by me: https://www.thingiverse.com/thing:2719188) and the filament grind an the plastic of the extruder filament guide. You need a nut für m4 screws respectively a nut with ca. 7 mm (6,85 mm) diameter.
