Z-Axis Cable Chain Stepper Mount

Just a clean simple z-axis cable chain stepper motor mount. This frees up the back rail to be used for other things, and clean up the look a bit as well.

**Requires:**
2 x M3\*6mm or M3\*8mm screws

Works great with this [Z-Axis Cable Chain End](https://www.thingiverse.com/thing:3577620).

Thanks johnniewhiskey for your great chain.
