TPU Damper Feet for Dual Rail 40mm Extrusion

thingiverse

My printer had begun to vibrate noisily and shake my desk so I tried to quiet it by adding dampeners, something TPU could be useful for. Searching around I found things which I liked partially, the dampener body on one, the feet on another, even better feet on a third. Thus I remixed. My fav is the version with the claw-like feet since it is so easy to attach or remove to the extrusion while the other version with 2 feet at the sides looks more robust but is a pain to get in when you cannot slide it in from the ends. This thing is meant to be printed in TPU. Since it has a simple shape, no overhangs or travel, I printed it with 0.3 mm layers and at 80 mm/s which came out nicely. (That was actually a test run for my 'Poor Man's Ball Bearing Filament Spool Holder' https://www.thingiverse.com/thing:4552666 ) I made it (and printed it on) an Ender 3 but it should be useful on any other printer with that kind of extrusion. It does reduce the transmission of vibrations by much. In my case, however, printer parts (like an added drawer, electronics box etc.) suffered from and chimed in to the vibrations and I ended with replacing a damaged hot end fan which was the source of it all.
