This is a Proper fitting and ribbed (wink) Spool Adapter for the Eryone Cardboard Spools. Working for the Bambu AMS. I utilize OrcaSlicer and use:
Layer Height: 0.2
4-5 walls
4 top/bottom shell layers
Seam Position: Random
Seam Gap: 3%
Also, I have COPIOUS amounts of ABS so that's what I've been using to make all my adapters, however PLA, PETG etc. etc. can all work just fine.
The author remixed this model.
After a few changes to the overall radius and height, this Adapter now fits nice and snug on the Cardboard Eryone Spools. If I come in contact with any differently sized cardboard Eryone spools in the future, I will re-visit this model and make adjustments.
