We’ve been having a good old time with this over on the Pocket Knife community, but I figure there’s probably a lot of crossover with this crowd as well.
I’m sure you’ve seen various clever little one piece utility knife blade holders on Thingiverse and so forth, and while they’re quite functional I don’t think they’re nearly as overwrought or silly enough, nor require quite enough components.
Rather than repeat my entire post from there over here, I’ll leave you with these:

I’m replying aside my original reply because I missed a detail here. My printer is the OG X-Plus, and does not share the same feature set as their current generation 3 models. My PLA print speed is 60-100 mm/sec depending on my needs and it’s not capable of going much faster than that. The OG X-Plus is a traditional gantry printer and is not a CoreXY setup like their newer machines. It also does not run Klipper, but that has not been an issue for me yet. (And you can manually control the machine via serial, with the pins hidden in the mainboard under the bottom deck plate. You can run it with OctoPrint or Kipper on an external Pi or other microcontroller board. I have a Pi hooked up to mine but I only use Octoprint for monitoring since the Qidi fork of Cura slicer can remote start/stop the printer natively as well as upload Gcode to it.)
The new models appear to be a little more comparable to the Bambus in terms of technology and speed – minus the filament exchanger system, which I personally think is dumb.
Don’t get me wrong, I like the multiple color print idea. But if I ever do that I will definitely get a dual or multi-extruder machine instead. The Bambu AMS wastes an absurd amount of filament on material change, and in highly detailed or sub-optimized prints can turn out to spend more weight in filament purging and pooping out the excess from color changes than actually winds up in the finished model.
