For now I'm working on a RepStrap 3D printer, to accomplish the project you can see on my website. I have a bunch of ideas that for some reason I was not able to make/complete, but since I discovered the Arduino world and how "€asy" it is to make a CNC machine, I found that finally I found a way to make the needed tools to bring my ideas to life. I am currently working on my RepStrap 3D Printer I'ble, so soon I'll publish it. After that, many others will come out!
