My intention was for winding 1Kg SunLu spools without the need for multiple centering discs for varying manufacturer spool hole sizes. This should work on most 1Kg spools. The 1 Kg SunLu spools are narrower than Bambulab spools so you will need to have a longer PTFE tube and the shorter Filament Guide and move the PTFE forward into the inner part of the SunLu donor spool edges so the filament guide guides better. Move the short PTFE tube guide to the end of the slot toward the gear side
