Tired of listening to your 3D printer buzz and vibrate its way through another print from the next room? These plastic feet allow you isolate your printer from the surface it's sitting on, quieting it considerably. UPDATE: Added a version to fit the double-thickness wall on the front and back of the i3 frame. These plastic feet snap onto the bottom of the wood frame and provide a 3/4" round mounting location to stick on 3/4" Sorbothane hemispherical bumpers. The Sorbothane bumpers do all the work, effectively quieting the printer. Often, the majority of the sound is transmitted as vibration into the table and floor, where it resonates and transmits into the room--especially at certain frequencies. For the ~13lbs of the MakerFarm Prusa i3v, I used six 3/4" hemispherical 70 durometer Sorbothane dampers. The dampers are tuned, so using too many or too few, will reduce their effectiveness. For maximum effectiveness, set the printer on a heavy, flat surface, like an 18" Travertine tile, available at most home centers for less than $10. These are the dampers I used: http://www.amazon.com/gp/product/B005JRN0WO To quiet your printer, order these Sorbothane bumpers: http://www.amazon.com/gp/product/B005JRN0WO Print six plastic feet, stick dampers to them, and snap them onto the bottom of your printer--two on the Y idler plate in the front, two on the Y motor plate, in the back, and two on the frame behind the Z motors. Two versions of the foot are provided: one for the normal i3v single-wall frame, and one for the double-thickness frame parts at the front and back of the i3. For best results, set the printer on a heavy, flat surface, like an 18" Travertine tile, available at most home centers for less than $10.
