Voron 18mm high round foot with mixed filaments

User can adjust sound deadening by slicing foot with different number of perimeters and fill pattern/density. I used Ninjaflex, two perimeters and 15% adaptive cubic infill. The short foot height with two perimeters provides enough stiffness to support 300mm trident printer. The 15% fill provides good lateral travel absorption. Adjust settings to your liking. This design removed majority of sound transmitted through heavy table to room below hobby room.
