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 affected 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:
Eventorbot has met its funding goal!
Well, I'm speechless and overwhelmed with all the support. I will like to say a BIG thank you for all the support, kind words, and to all the backers. To be able to share and have your interest in something I created is a great feeling. Everyone of you guys have made something that was a big dream become reality. Eventorbot, as a 3D printer is now going to happen! You will have no regrets in owning a Eventorbot, our machine will be a strong contender.
Thank you... thank you... thank you...

For Kickstarter pledges who did not pledge for the full kit.
If you pledged just for the plastic parts or the plastic bed, changes needed from the parts list:
Change to linear rods. Instead of:
(6) 10.5" long, 8mm linear rod.
Change to:
(4) 10.5" long, 8mm linear rod.
(2) 16" long, 8mm linear rod.
Change to pexi/glass bed. Instead of:
pexi/glass size: 8.5"(216mm) x 11"(279.5mm)
Change to:
pexi/glass size: 8.5"(216mm) x 16.5"(419mm)
With that little change, your machines Y axis will increase print size by 4" (Your machine will now print 6"x10"x6").
Here is what your machine will look like (googlesketchup/SKP file):

If you pledged for the plastic parts, metal frame, + or - the hot head bracket, changes needed from the parts list:
Change to linear rods. Instead of:
(6) 10.5" long, 8mm linear rod.
Change to:
(2) 10.5" long, 8mm linear rod.
(2) 16" long, 8mm linear rod.
(2) 13" long, 8mm linear rod.
Change to pexi/glass bed. Instead of:
pexi/glass size: 8.5"(216mm) x 11"(279.5mm)
Change to:
pexi/glass size: 16.5"(419mm) x 10 3/8"(263.5mm)
With that little change, your machines Y axis will increase print size by 4", and the X by 2" (Your machine will now print 8"x10"x6").
