Sunlu 72mm Spool Center

This is a remix of the spool reel holders

I use Sunlu and they have a 72mm center hole

I remixed one of the 54mm spool centers

I printed my first one at a straight 72mm but seemed to be loose but did work

So I added 4x splines to the reel too to add a bit more depth BUT I have NOT tested it again as yet, but can gurantee you may need to file down or put into tinkercad to adjust to fit a 72mm reel better
