Hello Gianni,

Great design!, I though about something similar a while ago but it remained just as an idea, I like your cam system to ensure a consistent positioning of the hot ends, my idea didn't imply moving them, it was just a servo system type of clutch to grip one filament or the other.
I see that you discontinued the 3mm version but is there any possibility I could get those files?, all my filament is 3mm and I have a lot!, of course I would go ahead at my own risk!

Again, great design.
