A CoreXY/Bowden design with a belt driven Z axis. This is a box design without the front end of the box, making the print area and maintenance, like changing a nozzle, easily accessible.

This is a simple, yet rugged design, weighing only 6 lbs and with 13x13x14" volume with a 8x8x6" build area. While assembly is pretty simple, the small size and rigidity of the design make shipping assembled printers attractive.
