Eventorbot
Eventorbot! Open source 3D printer. Simple with less materials. Frame is made of a single 4' long, 2 1/2" square tube (16 gauge/1.5mm/.0598" thick, cost: less then $20.00). With the design there is less plastic parts, stronger structure, all wires are hidden, and a more appealing/finish look.
The unit is supposed to resemble a robotic arm with hydraulic tubes. It was designed for prints to be less effected by vibrations. With the 1 solid frame, any vibrations of any axis will cause the other axis to move with it. For example: If the X axis causes a slight vibration/1mm movement to the right, the Z and Y axis will also move that 1mm to the right. This will result in a better print as everything will remain squared.

UPDATE:
Okay, so here is my current plans. I'm going to finish the tutorial videos and plans first (http://www.youtube.com/user/eventorbot should not take more then 3 videos). After that I will contact my metal company and see if they can use their plasma cutter to make the cuts and holes we need for our frames.
For those who do not have access to a 3D printer. I have had experience making molds and using urethane plastic. I will try to make molds of the plastic parts and mold it with urethane plastic. This plastic is very rigid and durable, and is equal or better then ABS.
Note: For those who have 3d printers. The main bed, that supports the linear rods will also be available, as many printers are not able to print it because of the size.

(optional) 1 set of printed decorative end caps (stl files listed on thingiverse.com soon).
(1) Set of screws. List: http://eventorbot.com/hardware.htm
(1) Sanguinololu 1.3a mother board with ramps. Ramps to be compatible to steppers (it should come with pin connectors and pins). Pic: http://eventorbot.com/pics/Sanguinololu%20board.jpg
(1) MK7 drive gear (gear to drive the filament). Pic: http://eventorbot.com/pics/mk7_drive_gear.jpg
(1) 4 foot of XL timing belt. PDF: http://eventorbot.com/pics/XL%20schematic.pdf
(4) Push button momentary end stop switches. Pic: http://eventorbot.com/pics/Push%20button%20momentary%20switch.JPG
(1) Bed. Aluminum or pexi-glass 8.5" x 11", 1/8" thick. (thickness does not have to be exact). Diagram: http://eventorbot.com/pics/bed%20diagram.skp
(4) Springs for bed (this box should have all the springs you need for any circumstances: http://www.homedepot.com/h_d1/N-5yc1v/R-100142075/h_d2/ProductDisplay?catalogId=10053&langId=-1&keyword=springs&storeId=10051#.UDZP5tXDCSo
(8) Rubber feet (bore holes need to be able to allow 10-32 screws) Pic: http://eventorbot.com/pics/rubber%20feet.jpg
(1) Roll of 1/4" black poly tubing. Cut to: (1)14" for hothead wires, (1)20" for filament feeder, (1)12" for bed to mother board tray connection. Pic: http://eventorbot.com/pics/hose.jpg
(6) Air pneumatic tube 6mm push in connector fittings. (Total Size 21mm x 12mm/ 0.82" x 0.47"(L*W) Thread Diameter 9mm/ 0.354) Pic: http://eventorbot.com/pics/hose%20connector.jpg
(1) 5.5 mm x 2.1mm DC power jack socket female panel mount connector. Pic: http://eventorbot.com/pics/DC%20Power%20Jack.jpg NOTE: If you choose to use a hotbed, upgrade this jack to something that can handle at least 13amps. As for your power source, you can use a Xbox 360 power brick. Xbox 360 power brick is 16amp and is more then enough to handle the power (under $20.00).
(1) Laptop charger 12 volt DC at least 5 amp. Pic: http://eventorbot.com/pics/power%20supply.jpg
(1) Hot end assembly (SKP file on diagram and how to build coming soon)
