prusa x carriage reinforced 4 lm8UU for Budaschnozzle with double cooling fan (hot end and part)

a more sturdy xcarriage for prusa mendel and Budaschnozzle with cooling duct for the upper part of the hot end and an another one for cooling the part if needed.

I haven't got the small fan for the UQCT so i redraw an other way to use the standard 40mm fan

I think the image is enough. i will post some pics as soon as possible.
every thing printed nicely 0.3mm nozzle 0.5mm slic3r 0.9.9
