Ninjaflex vibration isolation feet for Prusa i3 MK3 + MK3S

thingiverse

I originally printed these feet for my MK3S in Flexion X60 ultra-soft TPU on my modded Replicator 2, but I wanted this to be printable on the Prusa MK3S itself, which cannot print X60. I've included print settings for Ninjaflex that mimics the vibration-damping qualities of the softer X60 material. Compared to my X60 feet, I reduced the number of perimeters, and reduced the infill to replicate the suppleness of X60. These feet fit snugly into the extruded aluminum frame and might take a bit of work to fit in, but they won't shift or fall out once they're in! TPU sticks like crazy to PEI, so make sure you use some kind of adhesive as a protective layer to avoid damaging the print bed. I wipe on diluted white PVA glue, but I've heard of people having good result with glue sticks, as well.
