Z-Endstop Prusa i3 (Samelladrucker)

After building my Prusa i3 based on this kit: http://fpv-community.de/showthread.php?56521-3D-Drucker-Bastel-Workshop-wer-macht-mit I realized after the first printing, that the Z-Enstop mount must be improved.
I have therefore drawn following bracket. I use this been successful for several weeks. So the spacing between nozzle and pressure base is now possible to very finely adjusted.
