This is a poop scooper designed for Bambu Lab's machine. Sometimes, when the printer is in the process of heating and extruding material, it may stick to the walls and become difficult to detach. At such times, you may need to help it scoop out from the backside of the machine, if you know what I mean.

When using AMS, if too much poop gets stuck, there's a risk that waste material might be dragged onto the print bed, or it could stick to the wiping tower, and even adhere to the nozzle, resulting in a printing failure.
