Bambu A1 External Spool Adapter

After getting tired of my external spool flopping around while my printer uses the AMS, I decided to make an adapter spool that keeps the external filament roll in check. Internal diameter of the spool is 27mm to go overt the external mount spindle and the external diameter of the ends are 40mm to allow the filament spool to slide over with a 36mm diameter in the middle to keep it in place.This is my first public project (so be kind :)
