Found tiny 8mm ribbed rubber plugs inside my X1C – where do they belong?

Hi everyone,

I just found these two small, ribbed grey rubber/silicone plugs lying at the bottom inside my Bambu Lab X1C. They are very small, only about 8 mm in size.

Could anyone please tell me where exactly on the printer chassis these plugs belong and what their purpose is?

Thanks in advance for your help!


Looks like the z-spindle silicone sock.

Thanks - yes. Did not know. They are back in now.

Good. That’s one problem less to solve for you. Head for the next one. Don’t worry, sooner or later it will come. And when it will, we’ll be waiting to hear from you.
