Bought original anti-vibration feet from Bambu Lab for X1C. Soon enough I've found out they are useless and they will eventually pop out from the printer and might cause some serious damage to the printer when printing.
Bambu lab has released new version, so I asked them if there is a solution for the older version. Got stl from them to print and upgrade part that fits right into the original feet. Well, it looked good, but didn't work as anticipated. Printer couldn't finish calibration and I was getting multiple errors, cause it was shaking way too much.
Found a squash ball feet stl by @MIRCON and remixed it with the official solution from Bambu lab. it has now a part that fits right into the printer socked for the feet.
Printed with 0.2mm layer height, used blue squash balls, as they are harder, they fit perfectly and it works like a charm. It has finally passed the calibration and vibrations went down massively.



The author remixed this model.
Upgraded with official solution for anti-vibration feet version 1 from Bambu lab.
