Hey There! i have an old k1max at hand, which is big, noisy, wobbly, it cranks and trembles a lot especially while printing fast. These antivibration feet from "rotten-by-design" is a life saver.. These custom feet reduced the noise and vibration, i did not conduct a scientific before & after test but now my prints has visually less defect, especially the big ones which utilize the full build volume of k1 max. Thanks to: Designer: [%8471507906] Design Name: Creality K1 - Deluxe Anti Vibration Feet Adapter (Added v.2) (this can be assembled on any member of k1 series. For some reason i was unable to link the design directly, sorry for that) May the perfect first layer be with you! [%1786422819]
