Anycubic I3 Mega Spooladapter

This is a spool adapter to match the Anycubic spool holder rod.
Without this, the filament spool will keep jerking when there's a filament pull.
This solves this so it turns smoothly.

3 Version available:
For 73mm Spools such as Anycubic New version.
For 58mm Spools such as Anycubic, Patona.
For 52mm Spools such as Fillamentum.

EDIT:
Just got a Purple Anycubic Spool that is a new spool design.
It is 73mm, added that version.
