(PRUSA i3 MK2S) Antivibration feet

thingiverse

My 3D printer turned out to be louder than I had expected, and even though I put it into a build chamber, the movements caused my enclosure and cabinet to vibrate violently. In order to dampen the vibrations, I looked for and tried several solutions until I found one that worked well. One of those solutions was to put the printer on feet that used squash/racketballs for decoupling. As I did not find the available solutions stable enough as they were high and the balls were not fixed in place, and fell off the printer when lifted or moved. I decided to design my own solution using an 18 mm laminate chip/fiber board as a basis for my new feet. To reduce overall height, I drilled holes through the board and designed holders that put the ball as far into the board as possible. I also used holder covers to cover up the hole edges. The holders are screwed in place and fixed firmly into the board. The balls are fixed into the holder by a screw ring, which allows me to control the pressure of the ball, making it more or less firm. I used double yellow dot squash/racket balls for my setup. For me this setup reduced the vibrations substantially but did not fully remove them completely. I added a dimensional drawing of my board, including hole sizes and diameters. The board dimensions are designed specifically for a PRUSA I3 MK2S printer.
