I needed a way of mounting my big Colorfabb 2.2 kg spool on my A1 - and couldn't find one online. Thus I made this simple adapter to fit the standard Bambu Lab AMS holder, and angled it a bit to make the filament go to the std. small spool holder so that is easy to switch between spool sizes :-) 

I recommend attaching the “back feet” from the AMS build to avoid the mechine wobbling to much (I'm printing the feet now, after the first test with the 2.2 kg spool showed a lot of front/back wobbling - but the A1 still prints awesome…)

One of my first models, comments and suggestion for improvements are greatly apreciated :-) 

As always use at own risk ;-)

Have a great day.
