X axis belt tensioner

Here is my attempt at a X axis belt tensioner. it has served me well, and I hope it helps y'all out.
slots over the Right hand side nut trap on the z axis. also has bolt holes for fastening if required.
You will need a few bits of hardware, a roughly 20mm bit of 8mm thread bar, 2 nuts and 2 washers. i also used a spacer that came with my 608 bearings.
