The idea comes from Habony Norbert.
This is my version of a filament guide. Ideal if the spool is on the left or right side of the printer. It is plugged into the modified Z-top of the MK4/MK3. The angle can be infinitely adjusted by turning the holder. Very low friction from the filament. When the X-axis is moved quickly, the filament is not pushed back as much and stays well on the spool.
Three 608zz ball bearings and three M3x10 screws are required.
Material PETG, 30% infill, 3 perimeters
The author remixed this model.
This filament guide is inclined by 45 degrees. Guided by three 608 ball bearings. Therefore very low friction and tight guidance.
