Shapeoko / MegaOko Support

I'm 75% done building a large scale shapeoko, mixed with openbuilds rails (I should of just started with openbuilds system IMHO), but I decided the y rails could use some support so made this from a mash up of openbuilds source files....

I plan on just tapping the sides to add a shield on these. I have 3 per side... I'll add some better photos in a few days.
