Wanhao Duplicator I3 simple rear Z braces

A minimalist Z braces form Duplicator i3 that mount to the rear of the printer.
I designed this to replace the famous Azza's Z braces that was installed on my printer. I wanted a design that mount to the rear instead, but without being attached to the side of the frame and without reducing the maximum printing height.

Parts needed :
2x M8 threaded rods, 41cm long
8x M8 nuts
10x M3x10 bolts to replaces the originals.

I recommend to use my Y bracing feets with these Z braces :
