Dual extruder compatible with Prusa i2 and Prusa i3

This design provides a dual extruder compatible for Prusa i2 printer and Prusa i3 printer, by a system of bowden extrusion, to reduce the weight in the x-carriage and avoid vibrations during the print.
Each printer has a design for the x carriage. The rest of the pieces, are the same for both of them. The idea is to have the chance of changing easily your dual extruder from one printer to the other ( in case you have both models at home/work).
