The MOST delta printer is derived from the original Rostock (http://www.thingiverse.com/thing:17175). The design goal is to stay as true to RepRap ideals as possible, i.e. contain as many printed parts as possible. It's a very robust design and easier to build and calibrate than most delta printers.
Dr. Who fans will want to keep an eye out!
