This spool adapter downsizes a 72mm filament spool core diameter - Sunlu, Anycubic, Crealty, Hatchbox, et al to fit the Bambu Labs' AMS Lite rotary spool holder.
Updated version, inspired by MichaelRousseau3D's model on Makers World.
I was having durability issues with the original model (threads were stringing after a few weeks, as well as thread tolerance issues if printed above 0.2 layer height at +200mms. Also the outer ring was bit tough to grasp at times with my phat fingers. I think all those issues have been solved.
Tested on A1 Mini using default settings for any given layer height and Elegoo Rapid PLA+
Lastly, modified outer ring is easier to grasp and maneuver.
Will update once I try Sport and Ludicrous speeds.
Update:
Happy Printing in 2024!
PS - I included the Fusion360 file if anyone wants to play around with it.
