You can easily find rubber feet that has thin areas of rubber between
the feet. Get some brass tubing of the correct inner diameter and use
it to punch out circles. Sharpen the end of the tube with a bit of
sandpaper on the outside. It might be easier if you heat the tube and
melt through the rubber, but be quick to knock out the piece so it
doesn't melt all the way.
