Sorbothane Tile Foot

thingiverse

These are feet that slide onto the corners of a tile and have an indentation on the bottom to glue on a 1.5" Sorbothane hemisphere. It's not like you need to use 1.5" hemispheres, that was just what I designed it for, but you can glue on whatever rubber feet you prefer as long as they are less than 1.5" diameter. I can release a flat bottom version if requested. The tile I used was a 16" square with a thickness of 8mm.
