FT-5 Z screw alignment

I used this setup to align the two Z screws.

You'll need this:
3 GT2 60T pulleys(You could properly use 20T instead, though I'm not sure).
A GT2 1220mm(610mm) 6mm belt(Can be shorter).
608 ball bearings(Normal skating bearings) 6.
Some kind of 8mm rod as axle(I used a M8 threaded rod).
And finally 6 M3 screws(At least 45mm) and nuts.

The orientation of the middle part could be a problem, so it might be better to place it in reverse.
