Printrbot Lift Kit

These feet are based off of http://www.thingiverse.com/thing:92776 vibration foot / I modified this foot to increase the height and profile of the printrbot simple to increase its stability and ease some of the maintenance. Also I have a plan to increase the depth of the x axis platform and lifting it off the ground may allow me to move the x axis motor to the middle of the x plate to run in-between the rods instead of the end.
