Eventorbot is a 100% solid Open Source 3D Printer. You can build this desktop fabrication device with less materials according to the fact that it’s frame is made of aa single 4′ long, 2 1/2” square tube. This tube is giving the entire 3D printer a solid frame design, that reduces vibration during the printing process. All the wires are hidden within the frame, that costs less than 20$. The reduction of vibration results in a much better print result compared to other 3D Printer models.
