I've been given some linear rails, and the only thing I can think to do with them is build a large format 3d printer. I have two 750mm and two 670mm rails, two carriages each.

I know there are several open-source plans for printers, and I could use a cool project to work on. I already have a smaller printer to work with so I can already make a lot of the parts.

Has anyone done this before? What printer did you build, and do you have any recommendations and things to look out for?

I might go hardcore and build a welded frame for it.
