K8200 (3drag) dual leadscrew z axis upgrade with 2 Velleman K8204 leadscrew Kits

UPDATE : Corrected the Belt dimensions in the BOM

Here is my dual leadscrew z-axis mod for the K8200 (3drag).
It makes the z-arm way more sturdy and results in much smoother prints.

It is based on my hanging z axis mount (http://www.thingiverse.com/thing:648925) and represents it's next evolution step.

BOM is available in the instructions.
