Sunlu 5kg spool holder adapter

I was in need of a 5kg spool holder and found the Polymaker 5kg spool holder by UB3D here on Printables. After making it I quickly discovered that the spool holder shaft was too narrow for the Sunlu spool, causing the spool to drag on the ground.

I created this barrel shaft adapter to solve this issue and allow Sunlu 5kg spools to be used with the Polymaker 5kg spool holder!

This adapter shaft allows the use of Sunlu 5kg spools with the Polymaker 5kg spool holder.
