Tech2C, an Aussi 3d printing youtube, made this video where he shows how to eliminate and reduce the noise, vibration or rattling for his 3d printer.
He uses a HyperCube 3D Printer but his guide is applicable for almost any machine. Used upgrades are rubber feet, foam insulation, stepper motor dampeners or shock absorbers and TMC 2100 stepper drivers with stealthChop mode.
There is a great comment thread under that video with many additional ideas.
