While the filament form GST3D is super cheap and works pretty well I had a lot of trouble together with the Bambu Lab AMS. I have the Hydra Mod, But I assume the same problems are true for the vanilla version.
There is a ring adapter, but it did not work well with the Hydra mod as it was a bit too wide.
This new ring fits perfectly to the GST3D spools.
The author marked this model as their own original creation.
