Redsnapper

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+<ul><li>Generous thread tolerances and and a robust helix designed to allow printing at all layer heights on a 0.4 hotend. True and tested.</li><li>Tested up to 0.36 with a 0.6 hotend, no issues. However the standard settings for the 0.6 hotend result in very similar print times to a 0.4 Extra Draft (0.28).</li><li>The sweet spot appears to be a 0.4 hotend and 0.28 layer height if you don't feel like switching the hotend to save a few minutes.</li><li>2 perimeters are enough, I used 15% infill.</li></ul>Lastly, modified outer ring is easier to grasp and maneuver.Will update once I try Sport and Ludicrous speeds.Update: <ul><li>Prints fine on Sports Speed all layer heights with a .4 hotend </li><li>No go at Ludicrous, at least with the filament I used.</li></ul>Happy Printing in 2024!PS - I included the Fusion360 file if anyone wants to play around with it.
