Prusa i3 rework frame stabilizer

Parts needed:
-You will need to replace the rear Y axis threaded rods (at least 370mm, same with the frame width).
-2 threaded rods (about 400mm each) to connect the bottom and the upper parts.
-16 M10 nuts and washers
-Optionally you could drill one more M3 hole on the frame for the upper part (20mm below and between the other two holes).
-You may need to replace the M3 screws if they are two short.

note: the distance between the frame and the rear threaded rod is 100mm.
