Z-Level for Vulcanus V1

The parts are for this amazing printer (Vulcanus V1, CoreXY based): http://www.thingiverse.com/thing:821066

I didn't like the way the z-endstop was clamped to the smooth Z-rod so I've build my own easy-to-level-Z-parts.

You have to print my z-rodholder to screw the endstop in and my z-axis LM8UU Bolt part to put a M4 nut into it and screw a M4 screw through it.
Both parts will perfectly match each other, please see the images and you'll know how to use them.
If you wish you could print
