Awesome design! everything printed easily on my ultimaker. Used for everything PLA/PHA (colorfabb). I printed the wheels without any supports and they turned out awesome looking. Everything was printed with layer height of .2mm and infill of 20%.
No I need to go make the electronics. Planning on putting xbee in Wheely talking directly serial to the Polplu Qik. So I can make an remote arduino control unit.
