Prusa I3 Anet A8 dampened NEMA mount adapter

thingiverse

I decided to quiet down my printer a bit by installing industrial Nema dampers on the X and Y axis of my Prusa I3, but hit a snag: The rear motor clipped the subframe of the heated bed when I installed the damper so the X Axis was unable to home. So I designed an improved bracket for the X motor to account for the 4mm thickness of the damper. UPDATE: I realized that the rear motor mount was still transferring a lot of vibrations, so I removed it and replaced it with a piece of cut open vinyl tubing. I may design a printed part for that in the future. I also added pictures of my whole printer setup. The printer is set on a thick open cell foam mat with a wooden board on top. The board and the printer are also separated with vinyl tubing, which reduced noise even more. My printer is now really quiet, while still producing very high quality and reliable prints. UPDATE 2: I added an experimental rear support for the Y-Axis motor. This is my first ever design in Fusion 360, so it's far from perfect, but feel free to try it. UPDATE 3: I added a softer version of the motor support, the first one was too rigid and didn't offer the right amount of dampening. This one works fine for me, and hopefully for you too. I left the old version available because I thought it might be useful if you print in a flexible material like NinjaFlex, but for PETG (as I used), I strongly advise using the V3!
