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. Hope to have all the STL files for all the printable plastic parts later this week. Sharing this file for those who are interested. Link below is a Google SketchUp/SKB file. Google SketchUp is a free software from google. To view the file, please download Google SketchUp. From there, open the file and you can view the Eventorbot from any angle and take it apart as you like. Hope this will get you more familiar with the construction of the unit. The downloadable file is my blue print that I designed and used to build the machine. The accuracy is to the exact of my build.
