PCB Mill mount for Vert-X axis

Designed for Vertical X-axis competition.

PCB manufacture needs to be easier for reprap; countless numbers of printed parts can be made, but I see electronics as a real bottleneck. Just like 3D printing, the more accessible it is, the better the take up. To this end, I have started designing a milling carriage for the Vertical X-axis standard.

The idea is that the normal x-carriage can be unclipped from the x-axis, leaving LM8UU bearings on the linear rods, then this one can be clipped on
