Nắp Giữ Cuộn Dây Centauri Carbon

This is a spool holder cap for the body of the Elegoo Centauri Carbon. 

I hace my ECC in a IKEA closet/dresser and in order for me to change the spool of filament I had to remove the spool holder, mount the spool wo the spool holder and then reattach the spool holder and filament to the ECC. 

I decided to print a separate spool holder from this model: https://makerworld.com/en/models/979068-spool-roller-filament-holder-spool-holder?from=search#profileId-952427 (you could use whichever one suits your needs), but I didn't want the hole on the side of the ECC.
