BCN3D+ Z wobble solution

With this upgrade z wobble will desapear and X axis distance will increase up to 325mm

13/01/2015 - I reduced the ultra high quality of the .stl to high quality and I fix an error with the endstop x attachment.

03/02/2015 - I've make a new electronic support for this mod because I remove the original aluminiu plates.

02/03/2015 - I've upload the lower vertex support called (Suport roscada) because some users had asked for it. I repeat again that this part will make Z wobble so it's better without it.

19/03/2015 - Improved fixing bearing to "guia_z_motor" and "guia_z_no_motor". Also improved interior desing for the endstop z screw.
