Bambu refill compatible with SUNLU spools?

I have heard that the Bambu Filament refills are compatible with the SUNLU spools, but SUNLU seems to have 3 different sizes. Does anyone know which of the 3 spools works with Bambu Refills?

Is this what you are looking for?

Not particularly. That seems to be the older style spool, which I guess answers my question, that yes it’s possible with that adapter. But the 3rd Gen sunlu spool (with the extra inner rings) I believe solves this. Just wanting to confirm if bambu refills fit that style without any additional printing.

As far as I know the answer is no, but I found a use for the Sunlu spools. I buy Eryone carboard spool filament (they are a Sunlu sub-brand) and use them to refill the Sunlu plastic spools with an adaptor I made.

The opposite way around to your question - but might help with tracking down the answer. These Sunlu refills seem to fit fine into BL spools, so I guess Sunlu spools to go with these will probably also be compatible with BL refills.

Following the trail

I wonder if you will need to buy a sunlu refill too to get a sunlu spool suitable for the AMS

Interestingly the version with the spool is only £1 more.
