I didn't like the stock feet for the Mk3. I wanted to secure it down to my enclosure. So I created a set of feet that will lock into the 3030 extrusion of the MK3 with some M5 machine screw and T nut. Then just using a simple # bolt though the outer hole. Presto! The machine is not moving.

There are two different types of feet. The one with the extension is meant to support the front LCD as I've added a bit more clearance off the deck.
