The upgrade to the Printrbot Simple 1405 from the older maker edition makes the simple into a very competent printer. The design of the X axis slide makes it very easy to extend simply with longer rods and a new table and you are good to go. The only problem is that the base of the printrbot is not quite narrow and can wobble when printing quickly. To solve that issue I created these handy feet that screw into the existing frame screws. Just use some slightly longer screws and they snap right into place. They also raise the base of the printer slightly giving some more room for the nest of wires that connect to the board (it is more cramped in the smaller maker edition then the metal version).
