Z-Gantry Plasma cutter

I made this for the CNC plasma cutter I'm making, it is a Z Gantry and holds the torch, it is temporary design because the wood flexes to much wood thickness is 5.2mm it might work better with thicker wood but as soon as I can cut some metal I will redo the design to accommodate 1/8" metal. I uploaded dxf and dwg files and hopefully someone can use this design for something, the stepper motor is set for a Nema 23.
