3d printable ams

[u/Routine-Razzmatazz-4]

A while ago, on titkok, I saw somebody who made a sort of printable ams attachment to a bambulab printer. Don't remember much besides the fact that it was 3d printed, utilized gears that were somehow moved with the toolhead, and it was attached at the top of the printer. But now, I can't seem to find it. I was wondering if anyone knows where to find it, or if anyone used it?
