Description
February 9th Update:
It has been adjusted to be hollow, allowing for external filament spools, to prevent feeding failures caused by excessive width and high resistance in the AMS
——————————————————————————
Are you also troubled by your newly purchased filament spool unwinding (exploding spool)
To solve this problem, I made this spool unwinding savior, which essentially extends the central shaft of the official filament spool so it can be stably installed in the AMS (after extension, it can only be placed in the middle two slots)
Size is compatible, perfectly adapted
Easy to install, just like installing a normal filament spool, an additional stopper is provided to prevent the filament spool shaft from sliding
Installation Steps
1. Insert the shaft extender into side A of the filament spool (the side with the stopper pin)
2. Load the filament spool, aligning it with the stopper
3. Insert the retaining ring into side B of the filament spool
4. Assembly complete
