Attention! The coil consists of two parts!

Update: ESUN made new spool with diameter 76mm. Added v2 version

It is too expensive to print adapters. The adapter should provide excellent clamping of the side faces, I will try to come up with something.

Additional details:

2 or 4 M4x45 screws (acceptable M4x50, there may be problems with bulging)

2 or 4 M4 nuts

There was a problem called "Cardboard Coil", the solutions that ESUN offered work disgustingly. Of the 4 coils, their adapter fit only one. This solution solved the cardboard problem in the Bambu Lab AMS system.

Second problems - spool Bambu Lab it has a width of 58mm versus 52mm ESUN. For me, this led to a stall and entanglement of the filament in the spool
