Z-Mount Prusa i3 for Aluminium Frame

I had changed my original Part for the X-End to These: http://www.thingiverse.com/thing:514582 and then had a problem with my Z-Mount not fitting anymore.
So i tried enif's http://www.thingiverse.com/thing:341450 but i had to optimize it a bit for me.
The result is this thing.
No special print options required; i printed mine at 0.3 layer height as the quality didn't matter too much for me for this part.
