CR10 Mini Filament spool holder discs

thingiverse

Two discs do the trick to keep the filament spool centered - a must when dealing with shocking rotation. This setup works better than the standard spool (axle) holder for me. Note that not all rolls have identical openings, which can affect how they fit into the holder. The inner diameter of these discs is 33mm, making them larger than the original holders, and their side lengths start at around 50mm or more. A straightforward yet effective solution indeed!
