Hypercube Evo Z-rod update

i got tired of the pore desgin on the clamp that it did not hold my rods firm so the rods some times from nowere slipped down and hit the table. so i decided to change that.
the bottom mounts has a little stopper as well to keep the rods from going down. so even if the screw is not tightned the rod will never fall down.

Per request i updated the so The V2 is made to be used in stock setup with the bottom down. :)
