Wanhao Duplicator i3 v2.1 x axis belt tensioner

Because of the newer longer bearings for the x axis I needed to design a different belt tensioner compared to the ones I could find here on thingiverse. Maybe my design will also help others.

I figured out that the holes are too small thus I used a 4 mill drill and made them bigger. That happened accidentally not on purpose. I might later change the design.
