Prusa i3 MK3 Sorbothane or Felt Feet

thingiverse

**THIS IS AN OUTDATED DESIGN** that I am keeping as a reference for future improvements. These have been surpassed by steelfab's design found here: https://www.thingiverse.com/thing:3082188 - in his words, "it's like Brigandier's and jltx 's feet (for the MK3) had merged their styles." Not tested yet, but I prefer Brig's method of attaching them and JLTX's design with its low profile. Thanks to everyone who has liked and used this design, and thanks to steelfab for building on it and making it better! **UPDATE**: A lipped version is now available for up to 1" diameter pads! General consensus suggests the lipped version is not ideal, but someone requested it so I added it. If you're using something with adhesive, the non-lipped version is strongly recommended as it will provide a perfectly smooth bottom surface. **UPDATE 2**: Fusion 360 files have been added for those who want to customize this design to fit their own pad sizes or screw head sizes. Both flat and lipped versions are available. The stock rubber feet on the Prusa i3 MK3 are terrible vibrating abominations that create heavy vertical lines in prints. Testing on the Prusa forums has shown that having no feet at all is better than using the rubber option. I created these replacement feet to allow 1" sorbothane hemispheres to be attached. Sorbothane is an amazing material and much more suitable for this application than rubber. Please Google it if you're not familiar with its properties. This should also work for thick circular felt feet that can be found in most stores, if you prefer that option (i.e., maybe for a Prusa mounted to a cement block). **UPDATE 3:** After the sorbothane feet reacted chemically with the finish of my desk (they melted and fused with the lacquer!), I swapped to 1" felt furniture pads under these. The machine is a bit louder, but I'm getting better results than with the sorbothane. If I had to describe the sorbothane effect, I would say they are better at absorbing vibration than the stock rubber ones; however, they are still reactive, and they still take some time to work (they just do it faster than rubber). The effect is that length of time the ringing is happening is decreased, but IT IS STILL HAPPENING. With the more rigid felt pads, the machine can't bounce. This ends up being louder, but has a much better effect on eliminating artifacts.
