About this 3D model

There is a slot in the adapter that is meant to be lined up with the little bit of filament that pops out of the inside of the hole. This was designed for the SUNLU PLA Meta, but it also fits some of their other spools. The outer diameter is 2.87 in / 72.898 mm and the inner diameter is 55mm to fit the AMS lite. I can adapt this to other rolls if you comment the size of the diameter of the hole.
