This thing has moved to Youmagine https://www.youmagine.com/designs/makeymakey-gamepad so I don't also get sued by Stratasys... Junior loves playing Canabalt with his MakeyMakey, but said it was uncomfortable to hold. This controller was drawn by him and modeled by in RhinoJust print and stick the MakeyMakey ( http://www.makeymakey.com ) into this. I've included the Rhino file as well as the bare-bones box that I used for test-fitting.Don't know what a MaKey MaKey is? Check this great Youtube video http://www.youtube.com/watch?v=_DWQ6ce2Ags
