Matter3d - Cardboard Spool Ring for Bambu Lab AMS

The Matter3d spools are a bit smaller than all the other variations I've seen. I resized the original fusion file in Blizzards model to “197mm” diameter and it fits like a glove.

Update March 24 2023: I received a spool that was too large for this ring with my latest shipment. I reached out to Matter3d and they said they haven't switched spools, so its possible the one I received was off, or their spool manufacturer has a tolerance that goes beyond this spool ring.
