CNC Router Plasma Parts (metric).zip
Metric, recommend reducing the length of cuts along the bend lines of the parts that attach to the ballscrew nuts.
If you'd like to be able to order a kit of the cut and bent steel, or of the electronics, or of the entire router, or even a pre-welded router, leave a comment on the YouTube video indicating your interest. If there's a reasonable amount of interest I will set up a kickstarter and see if enough people want kits to make it financially viable. Approximate cost of a fully welded and painted kit, ready for assembly with all ballscrews and electronics would be about USD$3000. Router has a working area of 840mm x 840mm x 150mm.

#define CPU_MAP_2560_RAMPS_BOARD
Then you'll get these pinouts:
