This is a TPU-printable (27mm) foot for your prusa printer. I created this because I needed greater clearance under my Mk3 after adding a new front plate to the printer that included a Raspberry Pi3, and 3.5" TFT touch screen.
No need to print this at 100% infill…I used 20%, and it actually seems to dampen vibrations as well.
