!!! Take a look at the remix by [Miklos Kiszely](https://www.printables.com/fr/social/486882-miklos-kiszely/about) on [Printables](https://www.printables.com/fr/model/407688-bambu-lab-p1-x1-x1c-x1cc-filament-spool-switcher-w), it's way better than this work !!! Some of my spools are too large to fit into the Bambu Lab AMS, I have to transfer them on spool like [this one](https://www.thingiverse.com/thing:5536204). I had some issues with the original design. I've redesign the thing so that : - the frame is more tuff - the cranck is more easy to rotate - the gear ratio is exactly 1:2 (50 teeth on crank gear and 25 teeth on axle gear) - the power is transfered more smoothly by the double helical gears - the axles are in one piece and the spike is removed You can use the [right hand spool axle nut](https://www.thingiverse.com/thing:3918099/files) and the [centering discs](https://www.thingiverse.com/thing:3918099/files) from the original [thing:3918099](https://www.thingiverse.com/thing:3918099) for both axles, and the [series spool joiner](https://www.thingiverse.com/thing:3823334/files) from this [thing:3823334](https://www.thingiverse.com/thing:3823334). Needed extra stuff : For the cranck *2x 608ZZ ball bearing* To fix the spool joiner *4x M5 nuts* *4x M5 16mm screw*
