I downloaded the UMO frame and gave it a few changes.
Till now al parts that I bought were cheap and Chinese xD except the electronics. They're still not from Ultimaker itself, but still good quality.
I already have the axes and the motors, belts and pulleys and all needed screws. I think I'm only missing the printhead, ball-bearings and the printing bed (I can also just laser that), but I'm probably forgetting something...
I am also pretty nervous to start putting everything together, but really excited at the same time.
