Large format Rostock style printer, built with aluminum extrusions.
My plan is to design a large printer, emphasizing quality over cost. Ideally there will be the 'full' version, and then various lower cost options.
The design of the plastic parts contained here is complete - that's not to say they won't be updated, just that everything in here is functional.
I am working on build instructions in a blog over here: http://berthareprap.blogspot.com/2013/05/mark-4-finally.html I am currently constructing the very first machine, so instructions are coming out as I get build time.

350mm 2060 extrusion, HFS5-2060-350. This can be larger if you like, but you'll need to recalculate the triangles and rod lengths.
