Anet A6 Y-Belt tensioner and holder

I Build my own Screw and Plate for the "Anet A6 Upgrade tensor Y for pulley GT2 with teeth" ( http://www.thingiverse.com/thing:2255364 ) because the linked one is not exact enough for me ;-) At my Version the screw has a little Head above the thread. So it will stand in the right angle. without the head the end of the thread sets the Tensioner in a little angle an that makes the Y-Belt itchy and scratchy.
