K-Cup Holder - Single

thingiverse

For when you want to save a K-Cup for a second use, but do not want to leave it in the machine, place it on a table where it might leak, or get a contaminated bottom. The K-Cup will rest nicely on the rim, but a slight downward pressure will snap it gently into place for a firmer grip. You could drill a small hole in the bottom and mount this permanently with a screw.
