Add wider feet to a printrbot for improved stability.Print out two of these feet (note that a foot almost completely covers a 200x200 printer bed). The feet fit on the outside of the Z axis motors and can be connected to the printrbot base by extended rods.This thing is based on THE printrbot's base. You need the included pb-Base.stl file in order to compile this thing with the included OpenSCAD source.
