Prusa i3 Steel base mount

The Prusa i3 steel frame, especially the one with the 200 x 300 mm base that I have, isn't especially rigid especially laterally with both ends of the base being capable of being moved from side to side. To increase the rigidity of the base I mounted the entire printer to an 18 mm MDF base with six of these feet, 2 each at each end and 1 on each side one the back side of the Z stepper motor mounts. I made mine out of ABS but I guess PLA would work just as well.
