Vibration absorbing Sorbothane printer feet
Description
These are effective vibration damper and noise reducer feet for any 3D printer using 3030 extruded aluminum beams as the frame, like the Prusa i3 MK3S. This isn't exactly a remix, but it was inspired by [Plaidbear's design](https://www.thingiverse.com/thing:3496474). My reasons for making my own design: * I wanted to do something similar that minimized the amount of filament used. * I wanted more thickness under the screw heads. * I wanted the foot mounts to fit perfectly under the 3030 beams without sticking out on the sides. * I didn't want to remove end plates or otherwise disassemble anything on the printer. I had a bunch of 3030 T-nuts that I wanted to use up. * It was easy to do in Tinkercad. Plaidbear has [an excellent technical description](https://www.thingiverse.com/thing:3496474) of the properties of these feet and why you need six of them, so I won't repeat it here. I did observe, however, that while these feet completely absorb the vibrations that the printer would otherwise transmit into my desk, the printer does wobble slightly as the extruder and bed accelerate back and forth. As far as I can tell, this actually helps reduce ringing. If the extruder does a hard acceleration in the positive X direction, it is helped along by the printer giving way a bit in the negative X direction, making for a cleaner acceleration, and the printer's motion is then absorbed and heavily damped by the feet.
