Changes Anet A6 to a A8 or I3 style printer.
I designed this because i found that with the A6 style, with the belt on one side, whenever i tighten the X belt, because the belt is on only one side, the side with the belt tends to move towards each other while the other side move away, making a Trapezoid shape if you will.
This can be fixed by tightening the rods down so they won't shift, however i find the I3 design more superior in tacking this.
Distance between lead screw and linear rod is 17mm. Any prusa or A8 x axis will work.
