Bambu Lab Spool Centre Sleeve For Respooling

I've designed this to help with re-spooling filament onto bambu re-usable spools. It has a small filament holding hole which holds the filament snug while the initial layer is pulled onto the the bambu spool, this has worked wonders for me so I thought id share it to help others.   Tested to fit the All bambu spools.   Recommended material; ABS - should you ever need to put these is a filament dryer   Build Plate; Bambu High Temp Plate, The rough base finish using PEI Plate is ok but not Ideal.   Changes on Bambu Studio; 0.2mm standard layer height, 2 wall loops, Sparse infill density 25%, Sparse infill pattern Gyroid, Supports OFF, Brim OFF.
