Filament spool 52mm to 8mm adapter
thingiverse
With my Anet A8, the filament spool spins on an 8mm rod causing jerks as it swings around loosely due to loose rotation. To fix this issue, I designed a simple adapter that fits inside the spool and centers the axis of rotation precisely around the rod, resulting in much smoother filament feeding. UPDATE: The two halves of the adapter can separate because one M8 nut moves along the rod as the reel unspools. To prevent separation, I designed a simple spacer to take up excess space and keep them together. Print Settings: Printer: Anet A8 Rafts: No Supports: No Resolution: 0.2mm Infill: 20% Post-Printing: Print two adapters and place one on each side of the spool, then use extra M8 nuts to loosely hold them in place for secure positioning.
