About this 3D model

I used these parts of a full mounting kit, didn't need the z-axis support (yet) and i think the other brackets limits the range of the y-axis.Second problem was, there is a severe difference between the holes in the front-plate and the back-plate. So it needed some drilling to get the holes on the same height. The y-bars are at perfect level now. Changed the corner angles to match with the machine angleChanged overall sizeChanged the y-chaped holes (any force of the screw will break the part to easily)
