Prusa i3v Y-Axis Belt Tensioner

This belt tensioner is for the Y-Axis idler on a MakerFarm Prusa i3v. I've used it on my 10" model, but I believe it would work on the others. This uses all of the stock hardware for mounting (M3 screws, nuts, M5 screw, nut). Please see my youTube video for a quick explanation: http://youtu.be/0K3A8wpP3LI

Disclosure: I haven't put a lot of operation time on this part yet, so use it at your own risk. If you notice any erratic behavior from the printer discontinue use and post a comment.

If you have any suggestions let me know!

Thanks,
