Because the center hole of the eSun cardboards spools are just a tad smaller than other brands, the original great adapter from bigdog7 didn't work for me in the AMS. So, I have redesigned one specifically for eSun (but based on the original idea) from the ground up with a 54mm center hole diameter and it works great…finally!
EDIT 5/2/24: Now including the version for eSun (and 3DGenius) spools with a 53mm center hole.
