Logitech K520 keyboard foot

A replacement foot for the K520 (and possibly other) model of Logitech keyboard. There are two different versions available; one that uses the same rubber pads from the original foot if you manage to salvage them, and one that replaces those pads with plastic. Print the "Dome" part and glue it into the round hole on the "NoPads" part.
The feet should snap into place and function exactly as the original.
