CR10 Mini Filament spool holder discs

Just two discs to hold the filament spool more in center (avoid the shocking rotation). Works for me beter than the original spool (axle) holder. Please note that not every spool opening of the filament rolls are the same. The inner Diameter is 33mm for over the original holder, and the spool holder side is from 50mm and higher. Simple but effective :-)
