This is a remake of what was a box design (openbuilds.com/builds/corexy-enclosed.1362). After seeing David Bassetti's fresh air design at plus.google.com/DavidBassetti, posted to the OpenBuilds Google Plus, I started playing around with a more open design.
The design prints an 8x8x8 inch object and also encloses the PSU, Ramps controller, bowden driver and filament spool in a 17w x 16d x 15h area.
The design uses a CoreXY system running on idlers composed of F625zz flanged bearings. It also uses a bowden extruder design to take advantage of the speed capabilities inherent in a CoreXY system.
The Y axis uses belts instead of screws. The two belts run in between the two wheel guide uprights on each side. The two belts are run by pulleys attached to a drive shaft which is driven by one motor positioned below the build plate.
This looks like it will cost about $400 to build. I expect to start building on it in 2 weeks and will update either as the build progresses or upon completion.
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.
