I noticed that at high accelerations over time some of the Bambu Lab anti vibration feet would slide to the side, so after many prints they wouldn't be level anymore. The solution, a simple spacer that keeps all the feet at the same distance from eachoter, thereby keeping them level to the printer. It prints in four identical parts that simply slide into eachoter.
If needed the Anti vibration feet themselves can be found for print here: https://www.printables.com/model/979671-bambulab-new-anti-vibration-feet
