Custom Prusa I3 printer with easy extruder change

Hello!! After much procrastinating upload my printer design partly because I am always touching things ... I leave part of the design of my personalized 3D printer based on Prusa i3 customized, specifically the mars easy extruder change, being able to adapt a syringe for example, a "Drenel", bowden extruder or without bowden for example for flexible filament or simply to change extruders with different nozzle diameters.
