Anet A8 Y-Belt Tensioner

thingiverse

This tensioner is one I personally made to eliminate the dependency on the holes in the front frame piece that many other tensioners require. This allows you line up the Y-axis belt with the bed properly (side to side adjustment). The spacers included are what you use to set the tension in your belt as this tensioner acts as a clamp on the front frame piece. This tensioner WILL work with most front frame braces.
