Adapter to repair Eryone filament spools

Taking advantage of a small accident in which an ERYONE coil fell to the ground, and I accidentally stepped on it with my foot thus opening on one side, I re-adapted a job I did a short time ago, to repair the coil by completely replacing the cardboard sides now broken. So by following this little guide you can install this adapter directly inside the cardboard cylinder in the center of the coil. As always I also wanted to give my little personal touch, here too I added a cylinder in the center that can accommodate silica gel bags or spheres. The adapters are held together with 4 brass threaded inserts M3xH4xD4.2 inserted into the salt container, and everything joined together with 4 DIN_7380 M3x10 screws. Nothing complicated. I hope it is useful for you, have a nice day. I also put the link where you can find the material (step, stl) with the relevant profiles and settings for the filament. Thanks and good job.
