A simple X-belt tensioner for the Anet A8 (and A6?)

The original ended upp with an offset that made the bearings in Z carrige to make sounds. I remade it so that the belt is all linear, no weird sounds on my printer now.
Required is a M3 nut and a screw, 40-50mm should do it (spare from when I built the printer)
